This article will explain in detail how Java can add two integers and cannot use the + sign and other arithmetic operators. Xiaobian thinks it is very practical, so I share it with you for reference. I hope you can get something after reading this article.

Knowledge points used: binary bitwise XOR, equivalent to summation. (standard)

Binary is phase by phase and multiplied by 2, which is equivalent to summation (carry)

Breakthrough: when carry is 0, add and exit.

Public class Add {public int addAB (int A, int B) {/ / write code here while (Block0) {int xor = A ^ Bapter / sum standard int and = (A & B)
