How do you swap two numbers without using third variable in java?

Swapping numbers without using a third variable is a three-step process that’s better visualized in code:

b = b + a; // now b is sum of both the numbers
a = b – a; // b – a = (b + a) – a = b (a is swapped)
b = b – a; // (b + a) – b = a (b is swapped)

The following example code shows one way to implement the number swap method:

public class SwapNumbers {

public static void main(String[] args) {
int a = 10;
int b = 20;

System.out.println(“a is ” + a + ” and b is ” + b);

a = a + b;
b = a – b;
a = a – b;

System.out.println(“After swapping, a is ” + a + ” and b is ” + b);
}

}

The output shows that the integer values are swapped:

Output
a is 10 and b is 20
After swapping, a is 20 and b is 10
