從這一篇開始我們將看看Java 5之後給我們添加的新的對線程操作的API,首先看看api文檔:java.util.concurrent包含許多安全執行緒、測試良好、高效能的並發構建塊,我們先看看atomic包下的AtomicInteger.import java.util.concurrent.atomic.AtomicInteger; public class AtomicIntegerTest { private static AtomicInteger data =
一、如果是每個線程都執行相同的代碼,則可以使用同一個Runnable來實現共用public class MultiThreadShareData { public static void main(String[] args) { new Thread(new ShareData()).start(); new Thread(new ShareData()).start(); } static class
為什麼會有線程同步的概念呢?為什麼要同步?什麼是線程同步?先看一段代碼:package com.maso.test; public class ThreadTest2 implements Runnable{ private TestObj testObj = new TestObj(); public static void main(String[] args) { ThreadTest2 tt = new

在部落格中有登陸介面的文章http://blog.csdn.net/vestigge/article/details/8124674就不在重複了,直接看登陸的代碼,用Mina傳遞字串上節已經看過了,要實現傳遞對象,也非常簡單,只需要修改一下過濾器:chain.addLast("codec", new ProtocolCodecFilter(new
