Java Program to Swap Two Numbers

In this program, you'll learn two techniques to swap two numbers in Java. The first one uses a temporary variable for swapping, while the second one doesn't use any temporary variables.

To understand this example, you should have knowledge of the following Java programming topics:

  1. Basics of Java 
  2. Java Operators 
  3. Java Data types 


Program with Temp Variable :





The output of the program is :

before swapping
value of a:5
value of b:10
after swapping
value of a:10
value of b:5


Program without temp variable : 



the output of the above program will be:

before swapping
value of first:5
value of second:10
after swapping
value of first:10
value of second:5
