Add two numbers without using arithmetic operators

In this program we will see how to add two numbers without using arithmetic operators in java . We can use bitwise operators like & , ^ and << . Now we will write program for sum two numbers without using arithmetic operators(+  , – , % )

public class AddTwoNumbersWithoutArithmeticOperator {

	public static void main(String[] args)
	   {
		  int a =25;
		  int b =25;
	      System.out.println("sub of "+a+" and "+b+" ="+addingTwoNumber(a , b));
	   }
	   
	
	static int addingTwoNumber(int a, int b)
	   {
	      while(b != 0)
	      {
	         int carry = a & b;
	         a = a ^ b;
	         b = carry << 1;
	      }
	      return a;
	   }
	   
}

Output :

sub of 25 and 25 =50
