COMPLETE QUESTION:

What does this method do?

public static int foo(String [][] a)

{

int b = 0;

for (int i = 0; i<a.length; i++)

{

b++;

}

return b;

}

Answer:

Returns the value of b which is the dimension of the array

Explanation:

The method foo accepts a multi dimension array and returns the dimension of the array. A complete code implementation and call to the method is given below:

public class TestClass {

   public static void main(String[] args) {

   String [ ] [ ] arr = {{"gh","hj","fg", "re","tr"},{"","er","df","fgt", "tr"}};

       System.out.println(foo(arr));

   }

   public static int foo(String [ ][ ] a)

   {

       int b = 0;

       for (int i = 0; i<a.length; i++)

       {

           b++;

       }

       return b;

   }

}

The output from the code snippet is the value of b which is 2
