1、模拟多人爬山
package com.work.climb;
public class ClimbRunnable extends Thread{
private int time;
private int num;
public ClimbRunnable() {}
public ClimbRunnable(int time, String name,int num) {
super(name);
this.time = time;
this.num = num;
}
public void run() {
while(this.num>0) {
try {
Thread.sleep(this.time);
} catch (InterruptedException e) {
e.printStackTrace();
}
System.out.println(Thread.currentThread().getName()+"已爬100米");
this.num = this.num - 1;
}
System.out.println(Thread.currentThread().getName()+"爬到山顶！");
}
public static void main(String[] args) {
ClimbRunnable c1 = new ClimbRunnable(200,"年轻人",10);
ClimbRunnable c2 = new ClimbRunnable(500,"老年人",10);
c1.start();
c2.start();
}
}
结果示例：
2、模拟叫号看病
package com.java.doctor;
public class DoctorThread extends Thread{
private int number;//看病人数
public DoctorThread() {
super();
}
public DoctorThread(String name,int number) {
super(name);
this.number = number;
}
public int getNumber() {
return number;
}
public void setNumber(int number) {
this.number = number;
}
public void run() {
for(int i = 1;i<=this.number;i++) {
System.out.println(Thread.currentThread().getName()+":"+i+"号病人正在看病！");
}
}
public static void main(String[] args) {
DoctorThread special = new DoctorThread("特需号",10);
//将主进程重命名为普通号
Thread.currentThread().setName("普通号");
// special.setPriority(10);
// ordinary.setPriority(1);
special.start();
try {
for(int i = 1;i<=50;i++) {
//如果普通号到49号后，特需号还未看完，先暂停普通号，看完特需号再继续
if(i == 49) {
special.join();
}
System.out.println(Thread.currentThread().getName()+":"+i+"号病人正在看病！");
}
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
结果示例：
3、模拟接力赛跑
package com.java.race;
/**
* 模拟接力赛跑
* @author Administrator
*
*/
public class Race implements Runnable{
private int length = 1000; //剩余赛程
public void run() {
String name = Thread.currentThread().getName();
while(true) {
synchronized(this) {
if(length<=0) {
break;
}
length -= 100;
try {
Thread.sleep(200);
} catch (InterruptedException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
System.out.println(name+"接力!");
for(int i = 1;i<11;i++) {
System.out.println(name+"跑了"+i*10+"米");
}
}
try {
Thread.sleep(500);
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
public static void main(String[] args) {
Race r = new Race();
Thread t1 = new Thread(r,"1号选手");
Thread t2 = new Thread(r,"2号选手");
Thread t3 = new Thread(r,"3号选手");
Thread t4 = new Thread(r,"4号选手");
t1.start();
t2.start();
t3.start();
t4.start();
}
}
结果示例：
4、模拟网站抢票
package com.java.ticket;
/**
* 模拟网站抢票系统，有三个用户：桃跑跑、黄牛党、张票票，如果是黄牛党只允许抢购一张
* @author Administrator
*
*/
public class Ticket implements Runnable{
private int count = 10; //剩余票数
private int num = 0; //当前用户抢到的第几张票
public void run() {
String name = Thread.currentThread().getName();
while(true) {
//根据sale()方法返回值判断是否为黄牛党，如果是结束线程
if(sale(name)) {
break;
}
}
}
public synchronized boolean sale(String name) {
if(count<=0) {
return true;
}
count--;
num++;
try {
Thread.sleep(100);
} catch (InterruptedException e) {
e.printStackTrace();
}
System.out.println(name+"抢到第"+num+"张票，"+"剩余"+count+"张票。");
//判断线程名是否为黄牛党，如果是返回true
if(name.equals("黄牛党")) {
return true;
}
return false;
}
public static void main(String[] args) {
Ticket t = new Ticket();
Thread t1 = new Thread(t,"桃跑跑");
Thread t2 = new Thread(t,"黄牛党");
Thread t3 = new Thread(t,"张票票");
t1.start();
t2.start();
t3.start();
}
}
结果示例：
