Not an ArrayList. An Array. For some reason, my teacher (or rather, the lesson plan we are using) requires that we make a program that takes an array of integers and removes all the zeroes. So far I have: [CODE] public void remove(int index) { for(int i = index; i …

They format output. s formats strings, d formats integers, and f formats double precision floating point data (double). Basically you can use them to trim a string down so it only displays a set amount of characters ("%.2s", for two characters only as an example), rounds to a certain amount …

Why do they release their own version? Also why don't they allow Java on their portable devices? I'm looking for their specific reason, something besides "Apple are Nazis".

This probably isn't the best place for this sort of thread, but it's the most popular board on the web development forums and I suppose it's semi-related to PHP so... I've made a few small scale desktop apps with C# and Java (including a few games through XNA) but now …

[CODE] public class ArrayHolder { int[,] array; ReceivesArray r; public ArrayHolder() { array = new int[50, 50]; // array gets filled //... r = new ReceivesArray(array); } } public class ReceivesArray { int[,] receivedArray; public ReceivesArray(int[,] theArray) { receivedArray = theArray; } } [/CODE] I'm doing something like the example …

I usually make enumerations separate from classes, but when my CS teacher was teaching us about enums, he put it inside the class, and when it came time to set a variable of the enum outside of the class, he told us to just pass a string to the class …

I know that it's possible to "force" a class to have a certain function through interfaces, but is there any way to "force" a class to have and assign certain variables? Also, is there way to "force" a class to assign inherited variables?

I've been learning Java here and there for the past few years from high school classes, but I don't know if I have enough knowledge of programming to actually make something useful. What do you think someone should know to be considered a beginning programmer? I'm just trying to gauge …

I am making Tetris in Java. I have the Grid as its own class (extends JPanel) a menu bar (also extends JPanel) and a class for the main game window (extends JFrame). I created instances of the Grid and the menu bar inside the main game window class and added …

I have to have Tetris made in Java in 3-5 weeks, but I haven't started, and have no idea how to start. I'm not asking anyone to make the game for me, I just need a general idea of what to do to get things rolling. Firstly, what classes should …

Just curious.

I've taken a few classes in high school that used java (including AP Computer Science A/AB) and have a grasps on the basics of the language. However, I know nothing on making an actual application, since most of the projects we made in class were simple little things; their main …

1. I'd like to become at least competent with C++ (good enough to work on large scale projects or even get a job as a C++ programmer), how long do you think it will take? I have some experience with java, and am learning with the PDF version of [URL="http://www.amazon.com/Beginners-Guide-Second-Guides-McGraw-Hill/dp/0072232153"]this …
