This Java programming tutorial will teach you the methods for writing program to calculate swap of two numbers. Swapping is used where you want to interchange the values. This program will help you to increase your programming ability.
In this program we will see how we can swap two numbers. We can do this by using a temporary variable which is used to store variable so that we can swap the numbers. To swap two numbers first we have to declare a class Swapping. Inside a class declare one static method swap(int i, int j) having two arguments, the value of these arguments will be swapped. Now declare one local variable temp which will help us to swap the values. At last call the main method inside of which you will call the swap method and the result will be displayed to you.
Code of the program is given below
Output of this program is given below:
Before swapping i = 1 j = 2
After swapping i = 2 j = 1
