Java 多线程访问的经典例子.txt

package com.wallta.thread;

public class MyObject {

public MyObject() {
// TODO Auto-generated constructor stub
}

public static void main(String[] args) {

MyObject myObject = new MyObject();

ThreadA a = new MyObject().new ThreadA(myObject);
ThreadB b = new MyObject().new ThreadB(myObject);

a.setName("A");
b.setName("B");

a.start();
b.start();
}

// 多线程 启用一个方法，使用关键字 synchronized 是的方法 同步，避免线程安全的问题.
public synchronized void methodA() 
{
System.out.println("begin methodA threadName =" + Thread.currentThread().getName());

try 
{
Thread.sleep(3000);
