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: Basics of Java Java Operators 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 Follow my session on youtube :
Its all about the QA Testing and Automation. Happy learning
