Sum of two numbers with bitwise operator

Question

I am pasting the code to find the sum of two numbers with bitwise operator. Please suggest if it can be optimized. Thanks...

public static int getSum(int p, int          


        

Answer 1

I think below soln is easy to understand & simple,

public static void sumOfTwoNumberUsingBinaryOperation(int a,int b)
{
    int c = a&b;
    int r = a|b;
    while(c!=0)
    {
        r =r <<1;
        c = c >>1;      
    }
    System.out.println("Result:\t" + r);    
}
