Java polymorphism basics
|
<p>I am reading the SCJP book by Kathy Sierra. Polymorphism is little confusing. Could you please help me out with a real world example for the following: I understood that Polymorphism only works when you have overridden methods no matter if you do it via class or interface and on runtime JVM determines the method based on Object type.
<br/>Lets say Horse extends from Animal and it also overrides the eat() method.
What is the benefit of doing: <code>Animal a = new Horse();
a.eat();</code> over <code>Horse b = new Horse();
b.eat();</code> <br/> Eventually the result is going to be the same. I apologize its a very basic question but even all the senior developers in my team gave me all different answers.</p>

How to override a method which is used in the parent constructor?
|
<p>I'm having a design problem which I don't know how to overcome in java. I want to override a method that is called from the parent constructor. Here is a very simple example of the problem: </p>
<pre><code>public class Parent {
public Parent(){
a();
}
public void a() {
// CODE
return;
}
}
public class Child extends Parent {
public Child() {
super();
}
public void a() {
super.a();
// MORE CODE
return;
}
}
</code></pre>
<p>I know that the child class wont be initialized until the parent is constructed therefore the childs a() method wont be called. What is the correct design to overcome this problem?</p>

check for click on any child element
|
<p>I want to submit a form with JavaScript once any child element of a specific unordered list is clicked.</p>
<p>The code could will look somewhat like this but the number of list items can get very long.</p>
<pre><code><ul id="myList">
<li id="myListItem1">list item 1<li>
<li id="myListItem2">list item 2<li>
<li id="myListItem3">list item 3<li>
</ul>
</code></pre>
<p>It will not be possible to add an onclick to every li. Also,I may not be able to attach code to the ul tag so if it is possible to solve without attaching code to the ul tag that would be the best. Unfortunately libs like jquery, mootools etc. may not be used. The id of the UL will always be known and static but the id of the LI's will be unknown since they can differ in amount.</p>

jQuery loading screen on form submit with file response
|
<p>I have an HTML form. When submitted it creates an Excel file and returns it.
On all other forms I have a loading screen shown in the <code>onSubmit</code> function and hidden in the <code>document.ready</code> function, but when a file is returned, there is no <code>document.ready</code> and so my loading screen doesnt hide.</p>
<p>I tried jQuery form plugin with callback function, but this way I was not able to normally show the response page on the other forms. The same is the case with <code>$.post()</code> function with a callback.</p>
<p>All I want is to call my <code>loadingScreenHide</code> function when the form submit is finished and leave the rest as normal.</p>
<p>Any ideas? </p>
<p>Thanks.</p>
<p>Code i tryed is like:
with form plugin callback function (return true; doesnt seem to work) :
$('form').ajaxForm(function () {activateDeactivateScreen('hidden'); return true; });</p>
<p>or with post instead:
$.post($('form').attr('action'), $('form').serialize(), function () {activateDeactivateScreen('hidden'); return true; });</p>
<p>the 2 main problems are when i use normal submit i dont have a callback and when i get a callback i dont have the normal submit/page load</p>
<p>i also had the idea of changing my java server pages to save the file temporary and redirecting to a download, but this way i would have to change about 20-30 java sources, so i would prefer a javascript solution</p>

Adapter fetches and parses RSS feed to get its data - best practice?
|
<p>In a shared project, we have an Adapter class (extends BaseAdapter, implements ListAdapter). In its constructor, this class fetches an RSS feed from the internet and parses the returned XML document to obtain the data it will 'adapt'; the data is kept in a private class variable.</p>
<p>This is seen as the "Android way" of doing things by the author and is supported by the project lead.<br>
Can this be considered a "Best Practice"?<br>
Can it be justified on the grounds that it (may?) increase performance?<br>
Doesn't it violate the general Object Oriented Design (OOD) principle that a class should have only a "Single Responsiblity"?<br>
Are best practices for OOD or Java to be set aside in Android development?</p>

HTML5 Snake Game - add multiple food
|
<p>I have followed <a href="http://blog.new-bamboo.co.uk/2009/12/30/html5-canvas-snake-game" rel="nofollow">this guide</a> to make my snake game.</p>
<p>But now I want to add more then one food into the map.</p>
<p>Well, I tried putting rows with <code>makeFoodItem();</code> instead of just the default 1 row.
So like: </p>
<pre><code>makeFoodItem();
makeFoodItem();
makeFoodItem();
makeFoodItem();
makeFoodItem();
</code></pre>
<p>Which also made 5 foods. But the score wasn't added when the snake got them, and they was just removed, and didn't added a new one when it was taken.</p>
<p>So I went into looking at the Function <code>makeFoodItem()</code>, which looks like this:</p>
<pre><code>function makeFoodItem(){
suggestedPoint = [Math.floor(Math.random()*(canvas.width/gridSize))*gridSize, Math.floor(Math.random()*(canvas.height/gridSize))*gridSize];
if (snakeBody.some(hasPoint)) {
makeFoodItem();
} else {
ctx.fillStyle = "rgb(10,100,0)";
ctx.fillRect(suggestedPoint[0], suggestedPoint[1], gridSize, gridSize);
};
}
</code></pre>
<p>but I could not really figure out what to do there.</p>

<a href="http://stackoverflow.com/questions/4597513/onpress-onrelease-in-android">onPress/onRelease in Android</a> </p>

<p>When a user holds a button the button changes color, and when the user leaves the button, the button returns to it's normal state. </p>
<p>Is there an event that captures this ?</p>
<p>I tried searching for something like button.onStateChanged, but no luck.. </p>
<p>EDIT:
When the user long clicks I want to start the autoincrement</p>
<pre><code>// Auto increment for a long click
increment.setOnLongClickListener(new View.OnLongClickListener() {
public boolean onLongClick(View a) {
autoIncrement = true;
repeatUpdateHandler.removeCallbacks(mRepeatUpdateHandler);
repeatUpdateHandler.post(mRepeatUpdateHandler);
return false;
}
});
</code></pre>
<p>And when the user leaves the button with his finger I want to stop the autoincrement </p>
<pre><code>increment.setOnTouchListener(new View.OnTouchListener() {
public boolean onTouch(View v, MotionEvent event) {
if (event.getAction() == MotionEvent.ACTION_UP && autoIncrement) {
//Stop autoincrement
repeatUpdateHandler.removeCallbacks(mRepeatUpdateHandler);
autoIncrement = false;
}
return false;
}
});
</code></pre>
<p>This is the handler: </p>
<pre><code>RepetetiveUpdater mRepeatUpdateHandler = new RepetetiveUpdater();
....
class RepetetiveUpdater implements Runnable {
public void run() {
if (autoIncrement) {
increment();
repeatUpdateHandler.postDelayed(new RepetetiveUpdater(),
REPEAT_DELAY);
} else if (autoDecrement) {
decrement();
repeatUpdateHandler.postDelayed(new RepetetiveUpdater(),
REPEAT_DELAY);
}
}
}
</code></pre>
<p>But this only works when the user lifts his finger above the button, when he drags it to somewhere else on the screen, the counter keeps running, any ideas? </p>

<p>I have the below code for a simple console application in C#. Whenever I input the AIR rate for the second input I get "input string was not in correct format" as the error. What is the correct format and how do I incorporate it into the current code I have made? I am not familiar with different variable types.</p>
<pre><code>using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace ConsoleApplication1
{
class Program
{
static void Main(string[] args)
{
int AIR, MIR, PMT, IP, PP, ABorrowed, Term;
Console.WriteLine("Please enter the amount borrowed on your loan ");
ABorrowed = int.Parse(Console.ReadLine());
Console.WriteLine("Please enter the interest rate for your loan ");
AIR = int.Parse(Console.ReadLine());
Console.WriteLine("Please enter term of your loan in months ");
Term = int.Parse(Console.ReadLine());
MIR = AIR / 1200;
PMT = ABorrowed * (MIR/1-(1/(1+MIR)^Term));
IP = ABorrowed * MIR;
PP = PMT - IP;
Console.WriteLine("Your total payment for this month is "+PMT);
Console.WriteLine("Of that payment " + IP + " is interest rate");
Console.WriteLine("and the Payment Portion is " + PP);
Console.ReadLine();
}
}
}

Bring multi-dimensional array down (unnest) one level

<p>Althoug this works well enough, I am curious if anyone knows of a prettier way of doing this as this situation seems to come up quite often. </p>
<pre><code><?php
//Initialy, data is nested up in $some_array[0] ...
$some_array = array(array('somevar' => "someValue", "someOtherVar" => "someOtherValue"));
print_r($some_array);
</code></pre>
<p>Array ( [0] => Array ( [somevar] => someValue [someOtherVar] => someOtherValue ) )</p>
<pre><code>// Could the following line be achieved a more elegant fashion?
$some_array = $some_array[0];
print_r($some_array);
// Prints the intended result:
</code></pre>
<p>Array ( [somevar] => someValue [someOtherVar] => someOtherValue )</p>
<p>Does anyone know of a way to achieve this with a native function or in a more elegant fashion?</p>

Android - app not searchable in Android store

<p>I have a new app that I made and put in the store yesterday.</p>
<p>I am able to see it here: <a href="https://play.google.com/store/apps/details?id=com.problemio" rel="nofollow">https://play.google.com/store/apps/details?id=com.problemio</a></p>
<p>but there is absolutely no way I can see it in the app store when I search for any terms. Any idea how I can get it to show up in the app store?</p>
<p>It says that the app IS compatible with my phone so I don't see why it wouldn't show up for me.</p>

Taking vector size() out of loop condition to optimize
|
<p>fibs is a std::vector. Using g++, I was advised to take fibs.size() out of the loop, to save computing it each time (because the vector could change)</p>
<pre><code>int sum = 0;
for(int i = 0; i < fibs.size(); ++i){
if(fibs[i] % 2 == 0){
sum += fibs[i];
}
}
</code></pre>
<p>Surely there is some dataflow analysis in the compiler that would tell us that fibs won't change size. Is there? Or should I set some other variable to be fibs.size() and use that in the loop condition?</p>

Dynamically add input via jQuery, however all jQuery inputs do not receive focus styling?
|
<p>I am dynamically adding inputs to a form when a user clicks on an anchor tag that has the jQuery click event attached to it.</p>
<pre><code>$(".add-input").click(function () {
$("div.form-item").append(get_input());
});
</code></pre>
<p>The above function successfully adds new inputs to the form, however I have another jQuery function that adds styling to the currently focused input like so:</p>
<pre><code>$("input, textarea").focus(function () {
$(this).parent().addClass("cur-focus");
});
</code></pre>
<p>This function works great for inputs that were apart of the original form, however all the dynamically added inputs do not have the class added by the above event handler.</p>
<p>Both of these event handlers are inside of the $(document).ready function. </p>
<p>Is there a way for the dynamically added inputs to also be bound to my focus event handler on inputs?</p>

Remove array indexes or create array without indexes
|
<p>So basically I have array -</p>
<pre><code>Array (
[0] => Array
(
[name] => my_name
[year] => my_year
[other] => Array
(
[0] => Yes
[1] => No
[2] => Other_values
}
)
[1] => Array
(
[name] => my_name2
[year] => my_year2
[other] => Array
(
[0] => Yes2
[1] => No2
[2] => Other_values2
}
)
)
</code></pre>
<p>So basically I would remove the indexes from the last subArray which are both [other] arrays.</p>
<p>Well basically how I would like it to be displayed is -</p>
<pre><code>Array (
[0] => Array
(
[name] => my_name
[year] => my_year
[other] => Array (Yes, No, Other_values )
)
[1] => Array
(
[name] => my_name2
[year] => my_year2
[other] => Array (Yes2, No2, Other_values2 )
)
)
</code></pre>
<p>Basically without indexes.</p>
<p>Is it even possible, and if it isn't, then maybe it's possible at the creation of the array?</p>
<p>I'm creating it with the array_push(); function.</p>
<p>If you need my PHP code of the array_push(); function, just give me a notice.</p>
<p>Hope you understood what I ment, if something is unclear, you are welcome to ask me, I'll try to explain more :)!</p>

Why is my method returning None?
|
<p>I have the following method call:</p>
<pre><code>NCOLS = 3
NPEGS = 4
first_guess = []
print("calling first guess method")
first_guess = firstGuess(NCOLS, NPEGS, first_guess)
print("after method call: " + str(first_guess))
</code></pre>
<p>firstGuess method:</p>
<pre><code>def firstGuess(NCOLS, NPEGS, first_guess):
"""Used for setting up the first guess of the game"""
print("in firstGuess method")
for c in range(1, NCOLS + 1):
if len(first_guess) == NPEGS:
print("about to return first guess: " + str(first_guess))
return first_guess
else:
first_guess.append(c)
print("out of for loop, first_guess len is " + str(len(first_guess)) + ", " + str(first_guess))
if len(first_guess) <= NPEGS: #there were less color options than pegs
firstGuess(NCOLS, NPEGS, first_guess)
</code></pre>
<p>This seems to be returning <code>None</code> for a reason I cannot figure out.</p>
<p>Here is my output:</p>
<pre><code>calling first guess method
in firstGuess method
out of for loop, first_guess len is 3, [1, 2, 3]
in firstGuess method
about to return first guess: [1, 2, 3, 1]

Passing and returnging array to the functions
|
<p>I have created two arrays. I wanna pass these two array to any function. I am beginner with function so tried with rough code to achieve my task. As I have some values in $cntctnum and $cntcttype named array.</p>
<pre><code> $cntctnum = array();
$cntcttype = array();
$response = array();
function play_with_array($cntctnum, $cntcttype){
$contactnumber= $cntctnum[];
$cntcttype = $cntcttype[];
// some code to play with array.
return resultarray();
}
$response = play_with_array($cntctnum, $cntcttype);
</code></pre>
<p>Is this right way to pass function in array?
Is I need to declare $response as array before or when I return resultarray(), it will automatically consider it as array?</p>

Java Typecasting & Calling Methods Simultaneously
|
<p>Very new to Java.</p>
<p>I have a class called <code>GraphicsObject</code> and a class <code>Bug</code> that extends it.</p>
<p>I have an ArrayList that holds all GraphicsObject in it:</p>
<pre><code>private ArrayList<GraphicsObject> gc = new ArrayList();
</code></pre>
<p>Then I have a function that gets called every frame called updateObjects().</p>
<pre><code>public void updateObjects(){
for(int i = 0; i < gc.size(); i++){
if(gc.get(i).toString().equals("Bug") ){
(Bug)gc.get(i).moveNorth();
}
}
}
</code></pre>
<p>The typecasting fails and the moveNorth() method never gets recognized because the class GraphicsObject does not have that method, only Bug does.</p>
<p>Any solutions?</p>

How to revise java?
|
<p>Ok so this isn't 100% programming question, for which I'm really sorry, but still this is the best place I know to ask it.</p>
<p>In ~2weeks time I'll have a job interview, first they'll make me take a test from Java and I was wondering what's the best way to prepare for it? I bet it will be something similar to SCJP (but probably much easier), are there any (short) books, tutorials that are worth reading? I did order the SCJP book by Sierra/Bates but I won't be able to read it before the test.</p>
<p>Don't get me wrong I do have experience with Java etc. but I really want to get the job so I want to go there well prepared.</p>

Is it safe to always use === in PHP?
|
<p>I'm new to PHP and I just ran across a day-wasting bug because I didn't realize that the PHP == operator does type coercion similar to Javascript.</p>
<p>I know that Douglas Crockford recommends never using the == operator with Javascript, and to always use the === operator.</p>
<p>If I code in a manner that never assumes type coercion, can I use the same advice in PHP, and never use the == operator? is it safe to <strong>always</strong> use the === operator, or are there gotchas that I need to be aware of?</p>

How can I assign static pieces of information to randomly selected data with javascript?
|
<p>I've got a simple javascript program that I'm using for a project. To explain it simply, it just displays a random word on a html page from an external js file, say like Car, Bus, Train, Boat, etc. The word chosen each time is randomly selected. So, on one load it might say Bus, then another time it might say Airplane.</p>
<p>I want to assign static pieces of information to each of the words now, and I'm trying to figure out, what's the easiest way for me to implement this? For example, I still want the data to be randomly selected, but if it says Bus I want to show a picture of a bus or display some other data, but only when Bus is selected, and the same goes for all the other words.</p>
