How do u get the length of 2 dimensional array?

[Ravi Sathish]

Hi once again
How can I get the length of 2 dimensional array in a method?
to make myself clear:
main()
{
compute(emp);//method call
}
int[][] compute(int emp1[][])
{
int result =emp1[][].length;
// or how?
}
please help?

Hi Ravi,
Try running this and you should fully understand how it works:

public class MultiTest {
    public static void main(String[] args) {
        int[][] multi = { { 1,  2,  3,  4,  5},
                          { 6,  7,  8,  9, 10, 11},
                          {13, 14, 15, 16, 17, 18, 19} };
        int[] sing = multi[0];
        System.out.println("sing : " + sing.length);
        for (int i = 0; i < multi.length; i++) {
            System.out.println("multi[" + i + "]: " + multi[i].length);
        }
    }
}

Just try to think of a multidimensional array as being an array of arrays.
Hope this helps,
