一,什么是SingleThreadExecution模式?同一时间内只能让一个线程执行处理 二,例子 1.不安全的情况 用程序模拟 三个人频繁地通过一个只允许一个人经过的门.当人通过时,统计人数便会增加,并记录通行者的姓名和地址 门: public class Gate { private int counter = 0; private String name = "nobody"; private String address = "nowhere"; publ…
直奔主题, Single Thread Execution也称作Critical Section(临界区),范例如下: public class SingleThreadGate { public static void main(String[] args) { System.out.println("ctrl + c to exit."); Gate gate = new Gate(); new UserThread(gate, "Alice", "A…
注:本文的主要参考资料为结城浩所著<JAVA多线程设计模式>. 单线程执行模式(Single Threaded Execution Pattern)是最简单的多线程设计模式,几乎所有其他的模式都在不同程度上应用了该模式.先看一个程序,通过它可以体验多线程程序无法正确执行的场景,这里所写的是个关于“只能单个通过的门”的程序:有三个人频繁地.反复地经过一个只能容许单人经过的门,当人通过门的时候,这个程序显示出通过人的“姓名”与“出生地”,其代码如下: public class Gate { pri…
这里有一座独木桥.因为桥身非常的细,一次只能允许一个人通过.当这个人没有下桥,另一个人就不能过桥.如果桥上同时又两个人,桥就会因为无法承重而破碎而掉落河里. 这就是Single Threaded Execution.有时也称为Critical section(临界区). 这个模式用来限制同时只允许一个线程运行. 首先,我们先来看一个应该使用该设计模式,但是却没有使用的案例: 在这里要写一个程序,用来模拟3个人频繁的通过一扇只允许一个人通过的门.当有人通过门时,门上的记录器会递增通过的人数,另外还…

控制台程序. 程序总是至少有一个线程,程序开始执行时就会创建这个线程.在普通的Java应用程序中,这个线程从mian()方法的开头启动. 要开始执行线程,可以调用Thread对象的start()方法.在新线程中执行的代码总是一个名为run()的方法,这是一个公共方法,不带参数,也没有返回值.程序中除了主线程之外的其他线程总是在表示线程的对象的run()方法中启动. 如果希望用于表示程序中线程的类执行某些操作,就必须为类实现run()方法,因为从Thread类继承的run()方法什么也不做. 重点…
