Introduction
In this demo I have used NetBeans IDE 8.2 for debugging purpose. But you can use any java programming language compiler as per your availability..
Write a Java program to swap two variables
public class Javaexcercise {
public static void main(String[] args) {
int num1, num2, temp;
num1 = 30;
num2 = 50;
System.out.println("Before swapping : num1, num2 = "+num1+", "+ + num2);
temp = num1;
num1 = num2;
num2 = temp;
System.out.println("After swapping : num1, num2 = "+num1+", "+ + num2);
}
}Result
