Java流程控制06：While循环详解

hile

while(条件){执行语句}

package com.kuang.sequence;

public class whileDemo01 {
    public static void main(String[] args) {
        //输出1~100
        int i = 0;
        while(i<100){
           i++;
           System.out.println("输出值："+i);
        }
    }
}

package com.kuang.sequence;

public class whileDemo02 {
    public static void main(String[] args) {
        //死循环，服务器的请求响应监听可以使用，一般都要避免死循环
        while(true){
            //等待客户端连接
            //定时检查
            //......
