Info1.java

=================

package threads;

class Info1 {

public String getName() {
return name;
}

public void setName(String name) {
this.name = name;
}

public int getAge() {
return age;
}

public void setAge(int age) {
this.age = age;
}

public synchronized void set(String name,int age){
if(!flag){
try{
super.wait();
}catch (Exception e) {
e.printStackTrace();
}
}
this.name=name;
try{
Thread.sleep(1000);
}catch (Exception e) {
e.printStackTrace();
}
this.age=age;
flag=false;
super.notify();
}

public synchronized void get(){
if(flag){
try{
super.wait();
}catch (Exception e) {
e.printStackTrace();
}
}

try{
Thread.sleep(100);
}catch (Exception e) {
e.printStackTrace();
}
System.out.println(this.getName()+"<===>"+this.getAge());
flag=true;
super.notify();
}
private String name ="Rollen";
private int age =20;
private boolean flag=false;
}

ProducerInfo1.java

===================

package threads;

class ProducerInfo1 implements Runnable {
private Info1 info =null;

ProducerInfo1(Info1 info) {
this.info = info;
}

public void run() {
boolean flag =false;
for (int i =0; i <25; ++i) {
if (flag) {

this.info.set("Rollen",20);
flag = false;
} else {
this.info.set("ChunGe",100);
flag = true;
}
}
}

}

ConsumerInfo1.java

======================

package threads;

class ConsumerInfo1 implements Runnable {
private Info1 info =null;

public ConsumerInfo1(Info1 info) {
this.info = info;
}

public void run() {
for (int i =0; i <25; ++i) {
try {
Thread.sleep(100);
} catch (Exception e) {
e.printStackTrace();
}
this.info.get();
}
}
}

TestInfo1.java

=========================

package threads;

public class TestInfo1 {
public static void main(String[] args) {
Info1 info=new Info1();
ProducerInfo1 pro=new ProducerInfo1(info);
ConsumerInfo1 con=new ConsumerInfo1(info);
new Thread(pro).start();
new Thread(con).start();
}

}

运行结果：

=========================

ChunGe<===>100
Rollen<===>20
ChunGe<===>100
Rollen<===>20
