java两个线程循环打印_java循环打印 多线程
問題描述
Java多線程，循環打印”我是多線程”10次。
思路:
1 開啟5個線程 "我" "是" "多" "線" "程",控制鎖的等待 釋放順序
2 for循環10次
/**
* @Method
* @Author 孤獨的main()函數
* @Version 1.0
* @Description
* @Return
* @Exception
* @Date 2019/2/11 10:56

// 如果不滿足打印條件，則調用wait，一直阻塞
while (state % 5 != 0) {
try {

// 執行到這里，表明滿足條件，打印，設置state
// 調用notifyAll方法
