今天在班里学了自增操作,先看一个简单的案例:public class Test{
public static void main(String[] args){
int a=10;
int m=7+a++;// m=7+a a=a+1
System.out.println(a);//11
System.out.println(m);/

关于i++和++i的区别,我想大家应该大部分会说i++是先给先把i赋值给其它然后再自加,++i是先自加然后再赋值。如: int j=0; int i=0; j=i++; 那么j应该等于0,而j=++i; 那么j=1。我已开始也是这么认为

在讲 i++与++i之前先看两个在笔试面试中经常遇到的题目: 题目1//代码1
int x=2;
int b=(x++)*3;
System.out.println(b);
/*
输出结果为:6
*/题目2//代码1
int i=0;
for(int j=0;j<100;j++)
