1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 |
import java.util.Scanner; class SwapNumbers { public static void main(String args[]) { int x, y; System.out.println("Enter the number x and y:"); Scanner in = new Scanner(System.in); x = in.nextInt(); y = in.nextInt(); System.out.println("Before Swapping:\nx = "+x+"\ny = "+y); x = x + y; y = x - y; x = x - y; System.out.println("After Swapping:\nx = "+x+"\ny = "+y); } } |
Enter the number x and y:
30
10
Before Swapping:
30
10
After Swapping:
