How can I add two numbers without using operator in Java?

1. Iterative Solution to add two integers without using Arithmetic operator

  1. int carry = (a & b) ; //CARRY is AND of two bits.
  2. a = a ^b; //SUM of two bits is A XOR B.
  3. b = carry << 1; //shifts carry to 1 bit to calculate sum. }
  4. return a; }
