Can anyone help me about multidimensional java code here?

To create 2 multidimensional arrays size 3x3 use Math.random to get int value put in the arrays and but the value is between 1-9 after that add the two arrays get the result put in the new array and display all the arrays.

I already start some but when I compile it show ArrayIndexOutOfBoundsException: 3

int array1[][] = new int[3][3];
int array2[][] = new int[3][3];
int addarray[][] = null;

int i, j;

for(i =0; i < array1.length; i++) {
for( j =0; j < array1[i].length; j++)
array1[i][j] = (int) (Math.random() * 100);
array2[i][j] = (int) (Math.random() * 100);
}
for(i =0; i < array1.length; i++) {
for( j =0; j <array1[i].length; j++)
System.out.print(array1[i][j] + " ");
System.out.print(array2[i][j] + " ");

Anyone can help me ?

You're just missing the braces around the inner
"for" loops. As it is, the "j" loop iterates on the
assignment of "array1", then falls out to the
array2 assignment after "j" has been incremented
past the end of the array.

Once you put braces around *both* assignment
statements, the code works fine (I tested it).
