Program Listing

import java.util.*;

public class Two_Dimensional {

public static void main(String[] args) {

// TODO Auto-generated method stub

Scanner sc = new Scanner(System.in);

System.out.println();

         System.out.print("Two Dimensional Arrays in Java\n");

         System.out.println();

System.out.print("Give number of rows: ");

int rows = sc.nextInt();

System.out.print("Give  number of columns: ");

int cols = sc.nextInt();

 

int[][] a = new int[rows][cols];

System.out.println();

System.out.println("Enter " + rows + " X " + cols +" = " +

(rows*cols) + " integers:");

for(int i=0; i<rows; i++)

{

for(int j=0; j<cols; j++)

{

a[i][j] = sc.nextInt();

}

}

System.out.println("Here are those " + (rows * cols) +

" integers in a " + rows + " X " + cols

+ " 2D-array");

System.out.println(Arrays.deepToString(a));

sc.close();

}
