1、首先创建一个打印机对象
package cn.b.happy;
public class Printer {
Object o =new Object();
public void print(){
synchronized(o){
System.out.print("微");
System.out.print("冷");
System.out.print("的");
System.out.print("雨");
System.out.println();
}
}
public void print1(){
synchronized(o){
System.out.print("好");
System.out.print("人");
System.out.println();
}
}
}
2、创建两个线程分别为thread1 和 thread2 分别继承thread 和 是实现 runnable接口 包含 打印机 printer 对象
package cn.b.happy; public class MyThread1 extends Thread{ public Printer print; @Override public void run() { for (int i = 1; i <=500; i++) { print.print(); } } }
package cn.b.happy; public class MyThread2 implements Runnable { public Printer print; @Override public void run() { for (int i = 1; i <=500; i++) { print.print1(); } } }
3、测试类 实现runnable 接口的 线程 不能调用start()方法，所以创建一个Thread线程对象里边传实现runnable接口的类，从而实现开启线程
package cn.b.happy; public class Test { public static void main(String[] args) { Printer p =new Printer(); MyThread1 t1 =new MyThread1(); t1.print=p; t1.start(); MyThread2 t2 =new MyThread2(); t2.print=p; Thread t=new Thread(t2); t.start(); } }
