线程同步

我们根据以下例子来了解一下线程同步

首先我们来创建一个Pinter类

public class Pinter {
	public void print1(){
　　　　　　　　　//线程同步锁
		synchronized (this) {			
			System.out.print("位");
			System.out.print("高");
			System.out.print("权");
			System.out.print("重");
			System.out.println();
		}
	}
	public void print2(){
　　　　　　　　//线程同步锁
		synchronized (this) {
			System.out.print("谋");
			System.out.print("事");
			System.out.print("在");
			System.out.print("天");
			System.out.println();			
		}
	}
}

　　接下来我们来用两个类来操作一下(MyTread1,    MyThread2)

public class MyThread1 extends Thread{
       public static Pinter print;
      @Override
      public void run(){
         for(int i=1; i<=500; i++){
             print.print1();
             }
         }
    }

public class MyThread2 implements Runnable {
	public static Pinter print;
	@Override
	public void run() {
		// TODO Auto-generated method stub
		for (int i = 0; i <=500; i++) {
			print.print2();			
		}
	}	
}

我们用实现类来实现一下

public class Text {
	public static void main(String[] args) {
		Pinter p = new Pinter();
		
		MyThread1 m = new MyThread1();
		m.print=p;
		m.start();
		
		MyThread2 m1 = new MyThread2();
		m1.print=p;
		Thread t = new Thread(m1);		
		t.start();
	}
	
}
