JLabel[][] array index out of bound error

Question

I'm getting an array index out of bound exception on the following code. I used debugger and this is what happened.

JLabel[][] labelHolder = new JLabel[8][8]; 

    for(int i=0; i<8; i++){
        for(int j=0; i<8; j++){
            labelHolder[i][j] = new JLabel ();   <- error occur right on this line when i=j=0

I have not clue why this is because if I just swap out the i and j for 0 and 0, it work perfectly :S

The condition in your second for-loop checks against the value of i instead of j

for(int j = 0; i < 8 ; j++)

should be

for(int j = 0; j < 8 ; j++)

Use:

for(int j=0; j<8; j++){
             ^

for(int j=0; i<8; j++){ This line has the problem, it should read j<8.

In your second loop, your stop condition is mistaken: replace i < 8 by j < 8.
