The difference between i++ and ++i in java

#i means assigning the value first and then calculating, i means calculating first and then assigning the value.

The example is as follows:

package com.test;
 
/**
 * @author Administrator
 * @date 2018/6/9
 */
public class TestAdd {
 
    public static void main(String[] args) {
        int a = 0;
        int b = a++;
        int c = ++a;
        System.out.println("a:" + a);
        System.out.println("b:" + b);
        System.out.println("c:" + c);
    }
 
}

int b = a ; means first assign the value of a to b, and then calculate 1.

int c = a; means first calculating the value of a, 1, and then assigning the value of a to c.

If there is no variable to receive a or the value of a, simply using these two operations will make no difference in the result.

The same is true for a-- and--a.
