Write a Java Program to swap two numbers with using the third variable.

In this Example, we have made use of the Scanner class to declare an object with a predefined standard input object. This program will accept the values of x and y through the command line (when executed).

1	import java.util.Scanner;

2

3	public class SwapTwoNumbers {

4

5	public static void main(String[] args) {

6	// TODO Auto-generated method stub

7	int x, y, temp;

8	System.out.println("Enter x and y");

9	Scanner in = new Scanner(System.in);

10	x = in.nextInt();

11	y = in.nextInt();

12	System.out.println("Before Swapping" + x + y);

13

temp = x;

14

x = y;

15

y = temp;

16	System.out.println("After Swapping" + x + y);

17

18

}

19

20

}

Output:

Enter x and y
45
98
Before Swapping4598
After Swapping9845
