JAVA同步
两个线程共用的一个类的一个实例package com.syn.test;public class TestObject {private String name;private boolean flag=true;public TestObject(String name){this.name=name;}public synchronized String getName(){try{System.out.println("begin get");while(!flag){wait();}flag=true?(flag=false):(flag=true);System.out.println("over get");notify();}catch(Exception e){e.printStackTrace();}return name;}public synchronized void setName(String name) {try{System.out.println("begin set");while(!flag){wait();}flag=true?(flag=false):(flag=true);this.name=name;System.out.println("over set");notify();}catch(Exception e){e.printStackTrace();}}}
两个线程：线程TestThreadOne和TestThreadTwo.
TestThreadOne代码如下：
package com.syn.test;public class TestThreadOne extends Thread{private TestObject object;public TestThreadOne(TestObject object){this.object=object;}public void run(){while(true){object.getName();}}}
TestThreadTwo代码如下：
package com.syn.test;public class TestThreadTwo extends Thread{private TestObject object;public TestThreadTwo(TestObject object){this.object=object;}public void run(){while(true){object.setName("two");}}}
调用线程如下：
package com.syn.test;public class Main {public static void main(String[] args){TestObject object = new TestObject("object");TestThreadOne oneThread = new TestThreadOne(object);TestThreadTwo twoThread = new TestThreadTwo(object);oneThread.start();twoThread.start();}}
