//Write a Java program to swap two numbers without using temporary variable.
public class StudyViral_04 { public static void main(String[] args) { int x = 100; int y = 200; System.out.println("Output :: "); System.out.println("Before swap:"); System.out.println("value of x :: "+x); System.out.println("value of y :: "+y);
x = x+y; // here x = 100+200 = 300 y=x-y; // here y = 300-200 = 100 x=x-y; // here x = 300-100 = 200
System.out.println("After swap:"); System.out.println("value of x :: "+x); System.out.println("value of y :: "+y); } }
Output ::
Before swap:
value of x :: 100
value of y :: 200
After swap:
value of x :: 200
value of y :: 100
