Cloning object in JAVA
|
<p>I can not understand the mechanism of cloning custom object. For example:</p>
<pre><code>public class Main{
public static void main(String [] args) {
Person person = new Person();
person.setFname("Bill");
person.setLname("Hook");
Person cloned = (Person)person.clone();
System.out.println(cloned.getFname() + " " + cloned.getLname());
}
}
class Person implements Cloneable{
private String fname;
private String lname;
public Object clone() {
Person person = new Person();
person.setFname(this.fname);
person.setLname(this.lname);
return person;
}
public void setFname(String fname) {
this.fname = fname;
}
public void setLname(String lname){
this.lname = lname;
}
public String getFname(){
return fname;
}
public String getLname() {
return lname;
}
}
</code></pre>
<p>This is example shows right way of cloning as a in the books write. But I can delete implements Cloneable in the class name definition and I receive the same result.</p>
<p>So I don't understand the proposing of Cloneable and why clone() method is defined in class Object? </p>

Minesweeper number of mines java

<p>Hi so I am almost done with this program that creates the class minesweeper game. It compiles and runs perfectly and the game shows up in the GUI client program, but one problem occurs.</p>
<p>When playing, sometimes the a 1 will appear when it has more than 1 adjacent mine, or a 0 when there is actually a mine in one of the eight squares surrounding it. Any help/suggestions are gladly appreciated!</p>
<pre><code>private void countAdjacentMines()

// TO DO: STUDENT CODE HERE
for (int i = 0; i < mineField.length; i++)
{
for (int j = 0; j < mineField.length; j++)

Confused about GridView and INamingContainer?
|
<p>I have a nested GridView. In order for me to find the nested GridView, I have to do a FindControl on the Parent GridView, but I was under the impression that you only need to do this if the parent control implements INamingContainer and according to this <a href="http://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.gridview.aspx" rel="nofollow">link</a>, GridView does not implement from INamingContainer. Is there another reason?</p>

groupsumClump Problem
|
<p>Im struggling to get the below problem right for a quite a while sometime.</p>
<p>Given an array of ints, is it possible to choose a group of some of the ints, such that the group sums to the given target, with this additional constraint: if there are numbers in the array that are adjacent and the identical value, they must either all be chosen, or none of them chosen. For example, with the array {1, 2, 2, 2, 5, 2}, either all three 2's in the middle must be chosen or not, all as a group. (one loop can be used to find the extent of the identical values). </p>
<pre><code> groupSumClump(0, {8, 2, 2, 1}, 9) → true
groupSumClump(0, {2, 4, 4, 8}, 14) → false
</code></pre>
<p>The code is at <a href="http://ideone.com/Udk5q" rel="nofollow">http://ideone.com/Udk5q</a></p>
<p>Failing test case scenarios:</p>
<pre><code> groupSumClump(0, {2, 4, 4, 8}, 14) → false -->NegativeArraySizeException
groupSumClump(0, {8, 2, 2, 1}, 9) → true false --> X
</code></pre>
<p>i have really tried my best to make it work but alas its failing always.
Please Need your help SO experts to resolve this problem
I will be highly obliged and thankful to you,if you can spare a few minutes to look into my problem as well and help me in acheieving the desired solution.</p>

Simple jQuery syntax help, don't know where I've gone wrong
|
<p>I'm having trouble with a jQuery code at the moment, I know WHERE the problem lies, but I don't know what the problem is exactly. Probably very basic, but I'm new to this.</p>
<p>You can see a (non)working fiddle here: <a href="http://www.jsfiddle.net/CvZeQ/" rel="nofollow">http://www.jsfiddle.net/CvZeQ/</a></p>
<p>Basically I want to set different .click function based on whatever is selected (I have 5 image maps, each with a different #mapname, and want each to pertain to a different variable (answer1, answer2, answer3...) so as to store the selected 'answer' for each map.)</p>
<p>Here is the code I'm using for one of the maps:</p>
<pre><code> $(window).load(function(){
//Get cookies when page loaded
var useranswers=$.cookie('survery');
useranswers= JSON.parse (useranswers);
// do something with previous answers
//#shape functions
$('#shape area').hover(
function(e){
$('#'+ this.alt).addClass('hover');
},
function(e){
$('#'+ this.alt).removeClass('hover');
}
).click(
function(e){
$('img.selected-region').removeClass('selected-region');
},
function(e){
$('#'+ this.alt).addClass('selected-region');
},
function(e){
var answer1 = $(this).attr("class");
});
});
</code></pre>
<p>I know the problem lies somewhere with the .click function, but I'm not entirely sure what I've done wrong. Any help would be greatly appreciated.</p>

Python dictionary - binary search for a key?
|
<p>I want to write a container class that acts like a dictionary (actually derives from a dict), The keys for this structure will be dates.</p>
<p>When a key (i.e. date) is used to retrieve a value from the class, if the date does not exist then the next available date that preceeds the key is used to return the value.</p>
<p>The following data should help explain the concept further:</p>
<pre><code>Date (key) Value
2001/01/01 123
2001/01/02 42
2001/01/03 100
2001/01/04 314
2001/01/07 312
2001/01/09 321
</code></pre>
<p>If I try to fetch the value associated with key (date) '2001/01/05' I should get the value stored under the key 2001/01/04 since that key occurs before where the key '2001/01/05' would be if it existed in the dictionary.</p>
<p>In order to do this, I need to be able to do a search (ideally binary, rather than naively looping through every key in the dictionary). I have searched for bsearch dictionary key lookups in Python dictionaries - but have not found anything useful.</p>
<p>Anyway, I want to write a class like that encapsulates this behavior.</p>
<p>This is what I have so far (not much):</p>
<pre><code>#
class NearestNeighborDict(dict):
#
"""
#
a dictionary which returns value of nearest neighbor
if specified key not found
#
"""
def __init__(self, items={}):
dict.__init__(self, items)
def get_item(self, key):
# returns the item stored with the key (if key exists)
# else it returns the item stored with the key
</code></pre>

Why are filename underscores better than hyphens
|
<p>From <a href="http://homepage.mac.com/s_lott/books/python/BuildingSkillsinPython.pdf" rel="nofollow">Building Skills in Python</a>:</p>
<p>"A file name like exercise_1.py is better than the name execise-1.py. We can run both programs equally well from the command line, but the name with the hyphen limits our ability to write larger and more sophisticated programs."</p>
<p>Why?</p>

PHP call static workaround for PHP 5.2
|
<p>Is there are way to get __callStatic, or similar, functionality in PHP 5.2?</p>
<p>I'm finishing a PHP Framework and need to use this functionality for a Database ORM class. So for example you can use the code below to get data from column 2 and column 4 of the database table i.e. by declaring methods dynamically according to what you want (like rails I guess).</p>
<pre><code>Class::find_by_col2_or_col4();
</code></pre>
<p>I have already done this in PHP 5.3 and it works perfectly, but I'm trying to do the same for those using PHP 5.2.</p>
<p>Or is there some other way to retrieve the name of the static method and arguments using PHP 5.2?</p>
<p>Thanks.</p>

pyschools topic 3 ex 9
|
<p>I have made already 3 posts today about pyschools.com exercises i hope that's not too much. Anyway, the exercise asks me to write a function to convert the time to 24 hour format.
Here's an example: >>> time24hr('12:34am') '0034hr'</p>
<p>My function, which works fine in my IDLE: </p>
<pre><code>def time24hr(tstr):
am_or_pm = tstr[-2:]
first_numbers = tstr[0:2]
last_numbers = tstr[3:5]
if am_or_pm == "am":
if first_numbers == '12':
first_in_am12 = '00'
return first_in_am12 + last_numbers + am_or_pm
else:
return first_numbers + last_numbers + am_or_pm
if am_or_pm == "pm":
if first_numbers == '12':
return first_numbers + last_numbers + am_or_pm
elif int(first_numbers) > 9:
ok = repr(int(first_numbers) + 12)
return ok + last_numbers + am_or_pm
elif int(first_numbers) <= 9:
ok = repr(int(tstr[1]) + 12)
return ok + last_numbers + am_or_pm
</code></pre>
<p>However, in the pyschools website, when i run the code, it gives me the following error :
ValueError: invalid literal for int() with base 10: '1:'
What does this mean ? </p>

Not sure how to draw "poison dart"
|
<p>Sorry if the title is a little... vague. Anyway, I'm making a platformer using java and I've been trying to create a pressure plate triggered dispenser that shoots poisoned darts. The game is pretty much split up into a grid system, with each block being a spot on the grid. so far I've made it so that when the pressure plate is activated, it looks as if it's pressed down. I've also been able to draw it to the screen but it does not move or anything. This is the code I use to draw it to the screen:</p>
<pre><code>public void drawDart(Graphics g) {
if(Component.isPressed) {
for(int x = 0; x < block[0].length; x++) {
for (int y=0; y < block[0].length; y++) {
if(x == 91 && y == 35) {
block[x][y] = new Block(new Rectangle(x * Tile.tileSize, y * Tile.tileSize, Tile.tileSize, Tile.tileSize), Tile.poisonDart);
}
}
}
}
}
</code></pre>
<p>Unfortunately, with this code when I step on the pressure plate, the dart is drawn, but will not move. I've tried using x++ before but that doesn't move the dart at all.</p>
<p>Another problem is that I would like the dart to look like it's affected by gravity, which is hard to do when the game is split into a large grid system. Either way, what do you guys think?</p>
<p><em>Moderator edit (moved from OP comment):</em></p>
<pre><code>block[x][y] = new Block(new Rectangle(x * Tile.tileSize, y * Tile.tileSize,
Tile.tileSize, Tile.tileSize), Tile.poisonDart);
</code></pre>

programatically switching between jquery library and 3rd party library
|
<p>We are using a 3rd party java script library for functionalities like drag-drop, calender etc. Now are planning to move to jQuery for these controls & effects.</p>
<p>The 3rd party uses $(DOMElement) like jQuery to add the extension methods to the control(say converting a textbox to calender).
jQuery also uses the same syntax.</p>
<p>We are not completely replacing the 3rd party library with jQuery. So in some place $(element) should refer to the 3rd party library, while in some places in the same page, it should refer to jQuery. </p>
<p>Is there a way to programatically specify which which library the $(element) should refer.</p>
<p>Thanks in Advance..</p>

Python -- How do you view output that doesn't fit the screen?
|
<p>I should say I'm looking for a solution to the problem of <strong>viewing output that does not fit on your screen.</strong> For example, range(100) will show the last 30ish lines in your terminal of 30 height. </p>
<p>I am only looking to be nudged in the right direction and am curious how you guys have approached this problem. </p>
<p>What have you done when you run into a situation where you wish you could conveniently scroll through some large output? </p>
<h2>Best Answer</h2>
<p>Use the scrollback buffer on your terminal. </p>
<p>If you're using GNU Screen, it can be set with <code>defscrollback 1000</code> or any other number in <code>HOME/.screenrc</code>. </p>
<p>Use <code>Ctrl-a, [</code> to enter copy mode</p>
<pre><code>j - Move the cursor down by one line
k - Move the cursor up by one line
C-u - Scrolls a half page up.
C-b - Scrolls a full page up.
C-d - Scrolls a half page down.
C-f - Scrolls the full page down.
G - Moves to the specified line
</code></pre>
<p>The best part is <code>?</code> for reverse search, <code>/</code> for forward search while in copy mode. </p>
<p>Super convenient.</p>
<p>Thank you!</p>

parse name no spaces?
|
<p>When a user enters more than one space, my program doesn't properly print the user's name out. For example, if the user enters their first name followed by 2 spaces and then their last name, my program assumes those extra spaces are the middle name and prints the middle name as the spaces and the last name as the second string entered, even though only two strings were entered. How can I improve this issue so that the extra space a user may enter doesn't count as a middle or last name?</p>
<pre><code>public static void main(String[] args)
{
Scanner sc = new Scanner(System.in);
System.out.println("Welcome to the name parser.\n");
System.out.print("Enter a name: ");
String name = sc.nextLine();
name = name.trim();
int startSpace = name.indexOf(" ");
int endSpace = name.indexOflast(" ");
String firstName = "";
String middleName = "";
String lastName = "";
if(startSpace >= 0)
{
firstName = name.substring(0, startSpace);
if(endSpace > startSpace)
{
middleName = name.substring(startSpace + 1, endSpace);
}
lastName = name.substring(endSpace + 1, name.length());
}
System.out.println("First Name: " + firstName);
System.out.println("Middle Name: " + middleName);
System.out.println("Last Name: " + lastName);
}
</code></pre>
<p>Output: joe mark</p>
<pre><code>First name: joe
Middle name: // This shouldn't print but because the user enter extra spaces after first name the spaces becomes the middle name.
Last name: mark

Displaying same datagridview in different places (c#)?
|
<p>I'm working on a desktop application in C# (in Visual Studio 2010, framework 4.0). I have to display same (or slightly modified - without some columns) datagridview / table in different places. I'll get the data from querying different (local) files. I find it very consuming to make a new query for each table. Thus I thought about binding tables with query. But I don't know if it is the best way to do it. I don't know how "expensive" it is to bind data to gridview. Maybe it would be better to somehow show the same table, maybe put it in a panel an then display it properly (moving it to different positions/user controls according to the user's navigation).</p>
<p>These tables are not that big, but I'd need to display 4-5 of them in quite some locations and I don't want to waste memory with them because there are also some very large tables.</p>
<p>Any ideas?</p>
<p>Thank you for your time and answers.</p>

Understanding Cookies in PHP
|
<p>When the following code is run for the first time, it does not echo out the "var1" value but it does on browser refresh (f5), Why? As i understand when the browser sends the code to the server, setcookie() stores the cookie variable ("var1") to a client (browser) in a local file and puts the "var1" value available in global domain via $_COOKIE superglobal. </p>
<p>Since "var1" value is available immediately in $_COOKIE after the first server replies to browser's initial request, then why the "var1" is not echoed out. Is it that setcookie() stores "var1" value in client's browser on first request and only when the page is refreshed (2nd request) the browser sends back "var1" value to the server and then the server makes it available in the global domain via $_COOKIE function.</p>
<hr>
<h2> CODE</h2>
<pre><code><?php
setcookie("var1","5");
echo $_COOKIE['var1'];
?>
</code></pre>
<p>Kindly clear this for me. </p>

Huge data in C++ program during compile time
|
<p>I have around 30 XML files, which my C++ process (at run time) should parse and make some installation.</p>
<p>I felt, instead of using XML at runtime, why can't I write a script which will encode the XML files into my own structure and generate a C++ program which should be compiled and built?</p>
<p>What I mean is, my script should populate the encoded structure as a variable assignment in C++ program.</p>
<p>Something like</p>
<pre><code>class generatedCode
{
private:
unsigned char = ox11, ox22....
};
</code></pre>
<p>Then my C++ process will decode this and do installation instead of XML parsing.</p>
<p>My whole intention is the bring all the XML info by some means into C++ process memory.</p>
<p>Can someone please suggest, is this a good way? Do suggest any other ways of doing it?</p>

what is the difference between os.open and os.fdopen in python
|
<p>I am really confused when to use <code>os.open</code> and when to use <code>os.fdopen</code></p>
<p>I was doing all my work with <code>os.open</code> and it worked without any problem but I am not able to understand under what conditions we need <code>file descriptors</code> and all other functions like <code>dup</code> and <code>fsync</code></p>
<p>Is the <code>file object</code> different from <code>file descriptor</code></p>
<p>i mean <code>f = os.open("file.txt",w)</code></p>
<p>Now is f the fileobject or its the filedescriptor?</p>

C# application not running on different machines
|
<p>I have a C# application that loads fine on my development machine but fails to even start on Win2008 machine.</p>
<p>Checked Frameworks and they match up, Net 4.0</p>
<p>I immediately suspected the problem was arising from references to specific files that I was reading from and sure enough, using some test code I narrowed it down to a single line.</p>
<pre><code>public static string[] salesArray = (File.ReadAllLines("sales.txt").ToArray());
</code></pre>
<p>If I comment out the above line, the test app starts, if I leave it in, it fails. Any ideas?</p>
<p>I am copying the Debug directory to the second machine (sales.txt) within it.</p>
<p>This is the entire code. The app does nothing but open a blank window.</p>
<pre><code>namespace testServer
{
public partial class Form1 : Form
{
public static string[] salesArray = (File.ReadAllLines("sales.txt").ToArray());
public Form1()
{
InitializeComponent();
}

How to add additional JavaScript code
|
<p>I'm developing a mobile site and the template I'm using is based off of Jquery Mobile.</p>
<p>In the header.php file, the template I am using is making calls to CDN javascript files:</p>
<pre><code><link rel="stylesheet" href="http://code.jquery.com/mobile/1.2.0/jquery.mobile-
1.2.0.min.css" />
<script src="http://code.jquery.com/jquery-1.8.2.min.js"></script>
<script src="http://code.jquery.com/mobile/1.2.0/jquery.mobile-1.2.0.min.js"></script>
</code></pre>
<p>Since I'm basically pulling in the JavaScript from those URLS and it's not actually some .js file in a folder on my web server - how would I go about adding additional javascript code? Do I add it to my header.php? Get a special plugin that'll allow me to add additional javascript? The template doesn't give my any option to add additional code. So, not sure where the code would actually go...</p>
<p>Thanks in advance</p>

Multi-threading strategies? (Modifying a scene in a multi-threaded engine through an Editor)
|
<p>I'm trying to write an editor overtop a multi-threaded game engine. In theory, through the editor, the contents of the scene can be totally changed but I haven't been able to come up with a good way for the engine to cope with the changes. (ie delete an entity while the renderer was drawing it). Additionally, I'm hesitant to write code to manage locks at every instance I use an entity or resource that can be potentially deleted. I imagine there has to be a relatively more elegant solution.</p>
<p>Does anyone have any ideas or strategies I can start looking at?</p>
<p>Thanks!</p>

create listview programmatically with no xml layout

<p>I found this example to create a custom listview:</p>
<pre><code>public class UsersListActivity extends ListActivity{
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
String[] statesList = {"listItem 1", "listItem 2", "listItem 3"};
setListAdapter(new ArrayAdapter<String>(this, R.layout.list_item,
statesList));
ListView lv = getListView();
lv.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
Toast.makeText(getApplicationContext(),
"You selected : "+((TextView) view).getText(), Toast.LENGTH_SHORT).show();
}
});
}
}
</code></pre>
<p>However, they are using a xml layout for each row. Is this good practice? What if I wanted to create my own layout programmatically and utilize it in the adapter? </p>
<p>I guess it would be easier just to use the xml layout, but it would be nice to know</p>
