Write a program to interchange the value of two numbers without using the third variable.

public class KboatSwap
{
    public static void swapNumbers(int a, int b) {
        System.out.println("The numbers are:");
        System.out.println("a=" + a + " b=" + b);
        a = a + b;
        b = a - b;
        a = a - b;
        System.out.println("The numbers after interchange:");
        System.out.println("a=" + a + " b=" + b);
    }
}
