Java Program to swap two numbers without using third variable
Example:
public class SwapingTwoNumber {
public static void main(String a[]) {
int x = 25;
int y = 30;
System.out.println("Before swap:");
System.out.println("x value: "+x);
System.out.println("y value: "+y);
x = x+y;
y=x-y;
x=x-y;
System.out.println("After swap:");
System.out.println("x value: "+x);
System.out.println("y value: "+y);
}
}
Output:
Before swap: x value: 25 y value: 30 After swap: x value: 30 y value: 25
