Thanks...
I am able to print the elements of the array but i am not able to assign those values to the array ....
How to do that...
I just did a little change in my code...
import java.util.Scanner;
public class CreatingAMatrix {
    public static void main(String[] args) {
     // TODO Auto-generated method stub
     System.out.print("Enter the number of rows: ");
     Scanner scanner1 = new Scanner(System.in);
     int m = scanner1.nextInt();
     System.out.print("Enter the number of coulmns:");
     Scanner scanner2 = new Scanner(System.in);
     int n = scanner2.nextInt();
     System.out.println("The size of the matrix is : " +m+" x "+n );
     int[][] a = new int[100][100];
     for(int i=0;i<=m;i++)
         for(int j =0; j <= n; j++)
          Scanner scanner3 = new Scanner(System.in);
          int o = scanner3.nextInt();
         System.out.println();
     for(int i=0;i<=m;i++)
         for(int j =0; j <= n; j++)
          System.out.print(a[i][j] + "\t");
         System.out.println();
}I am getting an output as this
output:
Enter the number of rows: 2
Enter the number of coulmns:1
The size of the matrix is : 2 x 1
1
2
1
