Q10) Write a program in Java to input two integers into two variables x and y and swap their values without using a third variable.
x = 5
y = 3
After Swap
x = 3
y = 5
Program
import java.util.Scanner;
public class Q10
{
public static void main(String args[])
{
int x,y;
Scanner sc=new Scanner(System.in);
System.out.print("Enter value of x ");
x = sc.nextInt();
System.out.print("Enter value of y ");
y = sc.nextInt();
x=x+y;
y=x-y;
x=x-y;
System.out.println("After Swap");
System.out.println("x=" + x);
System.out.print("y=" + y);
}
}Output
Enter value of x 10 Enter value of y 20 After Swap x=20 y=10
