https://blog.csdn.net/weixin_39723337/article/details/80352783 题目:3个线程循环打印ABC,其中A打印3次,B打印2次,C打印1次,循环打印2轮一.Synchronized同步法思路:使用synchronized.wait.notifyAll的方法利用线程标记变量控制三个线程的执行顺序. /** * @author XDarker * 2018-5-17 */public class Main { public static voi…

主要是利用线程的wait()和notify()来实现 public class MyThread implements Runnable { private String name; private Object prev; private Object mine; private MyThread(String name,Object prev,Object mine){ this.name = name; this.prev = prev; this.mine = mine; } @Over…

python 多线程实现循环打印 abc 好久没写过python了, 想自己实践一下把 非阻塞版 import threading import time def print_a(): global value global lock global stop_flag while stop_flag: while True: if value == 0 or value == 3: break lock.acquire() value = 1 time.sleep(1) print("aaa&q…

问题描述: 现有多个长度相同的数组,现要求使用多线程将数组内的数交替打印. 如: int[] ai = {1,2,3,4,5,6,7}; String[] ac = {"A","B","C","D","E","F","G"}; 最终打印出 : 1A2B3C4D5E6F7G. 实现方法(1) 1.使用 import java.util.concurrent.locks.…

采用Thread+Semaphore实现,思路很简单 import java.io.IOException; import java.util.concurrent.Semaphore; public class PrintABC { public static int MAX_TIME = 10; public static class PrintThread extends Thread { private String printChar; private Semaphore curSem…

import threading import sys import time def showa(): while True: lockc.acquire() #获取对方的锁,释放自己的锁 print('a',end='') sys.stdout.flush() #释放缓冲区 locka.release() time.sleep(0.2) def showb(): while True: locka.acquire() print('b',end='') sys.stdout.flush()…

并发 练习代码 #include <thread> #include <vector> #include <mutex> #include <iostream> using namespace std; std::mutex mtx; std::condition_variable cv; char arr[] = { 'a','b','c' }; char message = 'a'; void test(int i) { ;j < ;++j){ s…

有两种方法:semaphore信号量和mutex互斥锁.需要注意的是C++11已经没有semaphore. C++ 并发编程(六):信号量(Semaphore) - 止于至善 - SegmentFault 思否 https://segmentfault.com/a/1190000006818772 线程按顺序执行(迅雷笔试题) - CSDN博客 http://blog.csdn.net/mafuli007/article/details/8488534 mutex - C++ Reference…

有一个经典的多线程面试题:启三个线程,按序打印ABC 上代码: package cn.javaBase.study_thread1; class MyRunnable1 implements Runnable { private Object prev; private Object self; private String name; public MyRunnable1(String n, Object p, Object s) { this.name = n; this.prev = p;…

题目:http://wenku.baidu.com/view/d66187aad1f34693daef3e8a.html 启动三个线程,分别打印A B C,现在写一个程序 循环打印ABCABCABC.... 本文分别使用wait.nofity和Semaphore来实现: wait.nofity版本 public class TestThread { public static void main(String[] args) { new Thread(new OrderThread(0,'A')…
