Question about my java program (Sorry xeo D:) - David - 07-03-2013

Hello I am kinda new to java, I've been messing around with it a lil for the past few weeks.

Now I created this program that would print out a 5x5 square using an 2d String array.

Here is my code:

Code:
package main;

public class Main {

    //Creating an 2D array of strings.

    public static String[][] screen = new String[5][5];

    public static void main(String[] args) {

        //Setting the array using some fancy for loops.

        for(int i = 0; i < 5; i++)

            for(int j = 0; j < 5; j++)

                screen[i][j] = j + ", " + i;

        //Printing the array using some fancy for loops.

        for(int i = 0; i < 5; i++)

        {

            for(int j = 0; j < 5; j++)

            {

                if(j == 4)

                {

                    System.out.println("");

                }

                else

                {

                    System.out.print(screen[i][j] + " | ");

                }

            }

        }

    }

}

The problem is that I'm getting this output:

Code:
0, 0 | 1, 0 | 2, 0 | 3, 0 | 

0, 1 | 1, 1 | 2, 1 | 3, 1 | 

0, 2 | 1, 2 | 2, 2 | 3, 2 | 

0, 3 | 1, 3 | 2, 3 | 3, 3 | 

0, 4 | 1, 4 | 2, 4 | 3, 4 |

Which is a 4x5 square and not a 5x5 one. Can someone tell me what the problem is?

(Xeo, please do not say that the problem is java itself Tongue

)

I would try using

Code:
public static String[][] screen = new String[6][5];

i think that it is messed up slightly in JAVA so that X goes -1

I'm wondering xeo, how many angry e-mails have you sent to oracle? Be honest.

I'm *kinda* new to programming, besides batch (Which isn't really a programming language) I don't know any language, and Java is an easier to learn language (I think). So I will be movin' to C or C++ or something

You should try BASIC; or if you want a starter launguage, try Python.

I know a tiny, tiny, TINY bit of basic. Pyton , naaah. Isnt that a scripting language?

RE: Question about my java program (Sorry xeo D:) - seankingman - 07-03-2013

I also only know a tiny bit of BASIC and a little bit of VB and C++. As for Python, consult Xeo.

Yes, it is a scripting language, do you want a coding language?

Yeh, like java or C

I don't see what your problem is with Python...

I don't have a problem with python, but I just don't feel like learning it because I already know a scripting language (batch). So I feel like thats, naah.

I understand, I don't really want to code per say, that's why i learned languages such as Perl Python and Lua.

Python is a coding langue to you can compile them to runables in py2exe or if you use jython by putting then in the jar and doing alitle rename ing.

RE: Question about my java program (Sorry xeo D:) - Xeomorpher - 07-04-2013

... That doesn't change the language, nor it's purpose.

Python is one of the most flexible langs I have played with, I often use it for scripting tasks, but it's main merit, is that I can write code in it so damn fast, which allows it to make our plugins: Super fast, and everyone can read everyone's code (apart from jer)

RE: Question about my java program (Sorry xeo D:) - fl3tching101 - 07-05-2013

As to Python yes, great language, but a little TOO easy for beginners, kinda teaches bad habits in my book. As to Java being an easy language to begin with, wash your fingers off with soap. I don't care what the interwebs say about it being easy, THEY LIE. Code in C++, script in Python. Simple answer, short, sweet, to the point, and that's not common cause I like to ramble but it be late. Happy coding/scripting!

"As to Java being an easy language to begin with, wash your fingers off with soap" But me palms are dirty too D:

C++ is not short Tongue

You gotta include EVERYTHING litteraly EVERYTHING.

RE: Question about my java program (Sorry xeo D:) - seankingman - 07-11-2013

I've just started getting into Java and it's actually quite fun. I made and modified Benny's Pong game, adding multiplayer support and a 'first to five' game objective.
I'm having trouble compiling it with NetBeans though.

RE: Question about my java program (Sorry xeo D:) - Chibill - 07-15-2013

Use eclipse it's easyer and can compile it on save in to your bin file,

xD; You're worse than me.

also, ideally, 'Use eclipse;* it's easier, and it* can compile on save into your bin file.' is better.

Burn F# ;-;

RE: Question about my java program (Sorry xeo D:) - Xray_Doc - 09-29-2013

So I just started learning code for Java (Using Eclipse in school) and I can understand about 1/4 of this stuff.

RE: Question about my java program (Sorry xeo D:) - VirtualPineapple - 09-29-2013

I are great dissapoint in you xcray

RE: Question about my java program (Sorry xeo D:) - Xray_Doc - 09-30-2013

Hey, take it easy. I just learned class, task, and other basic functions.
