Addition of two numbers without using operators in java?

Answer 1

I don't think this can be done. Why do you want to do it without operators, anyway? It is fairly simple to use them. - Of course, you could write a method that adds two numbers, but your method will internally still have to use operators.

import java.math.BigInteger;

public class MultiplyTest {

public static void main(String[] args) {

BigInteger bigInt1 = new BigInteger("5");

BigInteger bigInt2 = new BigInteger("8");

System.out.println(bigInt1.add(bigInt2));

}

}

Answer 2

It is however tricky,you have to use bitwise shift operator

int multiply(int x, int y) {

int m=1, z =0;

while(x>=m && y) {

if (x &m) z=add(y,z);

y <<= 1; m<<= 1;

}

}

return z;

The idea is to use repeated addition. You can do this with a "for" loop.
