Populating 2D Arrays
Apr 20th, 2007, 8:43am  
Forgive the simple question; it's been a while since I've done this, and Google isn't revealing the answer.  

I am trying to declare, then populate a 2D array with integers.  I've tried several variations of what is pasted below to little success.  Can some kind soul advise on proper syntax?  (Thanks.)

Code:

// - - - - - Attempt 1 - - - - - 

int[][] panels = new int[15][4];

panels [][]= 
    { 6,6,0,0,0,0,0,0 };
    { 7,8,0,0,0,0,0,0 };
    { 8,9,0,0,0,0,0,0 }; ...

// - - - - - Attempt 2 - - - - - 

int[][] panels = new int[15][4];

panels [0][]={ 6,6,0,0,0,0,0,0 };
panels [1][]={ 6,6,0,0,0,0,0,0 };
panels [2][]={ 6,6,0,0,0,0,0,0 };
panels [3][]={ 4,4,4,0,0,0,0,0 };...

1: You're geting your numbers the wrong way around [15][4] means 15 4-digit arays, not 4 15-digit arrays.

2: You ned some extra keywords/less [] in places.

Code:
int[][] a=new int[3][4];
a=new int[][]{ {1,2,3,4},{2,3,4,5},{3,4,5,6}};

int[][] b=new int[3][4];

b[0]=new int[]{1,2,3,4};
b[1]=new int[]{2,3,4,5};
b[2]=new int[]{3,4,5,6};
