Java Program To Swap Two Number

Here's a simple Java program to swap two numbers:

public class SwapNumbers {
    public static void main(String[] args) {
        // Define two numbers
        int a = 5;
        int b = 10;

        System.out.println("Before swapping:");
        System.out.println("a = " + a);
        System.out.println("b = " + b);

        // Swap numbers
        int temp = a;
        a = b;
        b = temp;

        System.out.println("\nAfter swapping:");
        System.out.println("a = " + a);
        System.out.println("b = " + b);
    }
}

This program initializes two variables a and b with values 5 and 10 respectively. It then prints the values of a and b before swapping. After that, it swaps the values of a and b using a temporary variable temp, and finally prints the values of a and b after swapping.
