Creating an Array

 // An array of 10 ints.
 int[] ints = 
        (int[])Array.newInstance(int.class, 10);
     
 // An array of 10 int-arrays.
 int[][] ints2 = 
        (int[][])Array.newInstance(int[].class, 10);
     
 // A 10x20 2-dimenional int array.
 ints2 = (int[][])Array.newInstance
      (int.class, new int[]{10, 20});
