                23                           System.out.println("Cube of the number "+ ar[i][j] + " is: "
                                               + ((int)Math.pow(ar[i][j],3)));

              The output of the preceding program is as follows:
              Enter a number: 3
              Enter a number: 4
              Enter a number: 6
              Enter a number: 7
              Enter a number: 5
              Enter a number: 8

              Cube of the number 4 is: 64
              Cube of the number 6 is: 216
              Cube of the number 8 is: 512

              Dynamic Way: Using InputStreamReader
              This is another technique to insert the values by accepting the values from the user.


                Program 19     Accept numbers into a 3 × 3 array and then calculate the sum of even numbers present in
                               odd positions.

                 1       import java.io.*;
                 2       class sum

                 3       {
                 4           public static void main() throws IOException

                 5           {
                 6               InputStreamReader isr  =  new InputStreamReader(System.in);

                 7               BufferedReader br= new BufferedReader(isr);
                 8               int n[ ][ ] = new int[3][3];

                 9               int i, j, s=0;
                10               for(i = 0;i<3; i++)

                11               {
                12                   for(j= 0; j<3; j++)
                13                   {
