Hi,

I'm trying to learn more about matrices in Java.

I am trying to read in two integer matrices A and B, then print

out the calculation for A + B, but I am getting an ArrayIndexOutOfBoundsException on line 21.

Any help would be greatly appreciated.

```
class MatrixAdd {
public static void main(String[] args) {
int array[][]= {{0,1},{3,4}};
int array1[][]= {{5,4},{2,1}};
System.out.println("Number of Rows= " + array.length);
System.out.println("Number of Columns= " + array[1].length);
int l= array.length;
System.out.println("Matrix 1 : ");
for(int i = 0; i < l; i++) {
for(int j = 0; j <= l; j++) {
System.out.print(" "+ array[i][j]);
}
System.out.println();
}
int m= array1.length;
System.out.println("Matrix 2 : ");
for(int i = 0; i < m; i++) {
for(int j = 0; j <= m; j++) {
System.out.print(" "+array1[i][j]);
}
System.out.println();
}
System.out.println("Addition of both matrix : ");
for(int i = 0; i < m; i++) {
for(int j = 0; j <= m; j++) {
System.out.print(" "+(array[i][j]+array1[i][j]));
}
System.out.println();
}
}
}
```
