To learn use of in case of a two dimensional array.

Program:

import java.util.Scanner;

public class TwoDimArray {

public static void main(String[] args) {

Scanner sc = new Scanner(System.in);

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

int r = sc.nextInt();

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

int c = sc.nextInt();

System.out.print("Enter elements of array :");

int arr[][] = new int[r][c];

for (int i = 0; i < arr.length; i++)//used length case {

for (int j = 0; j < c; j++) {

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

}

System.out.println("Entered elements of array are:");

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

for (int j = 0; j < c; j++) {

System.out.print(arr[i][j]);

}

System.out.println();

}
