Java 线程操作的相关方法

//线程的相关方法

//1,yield(礼让) 和 join(强制运行)
 /*class MyThread7 implements Runnable{
	public void run(){
		for(int i=0; i<5; i++){
			System.out.println(Thread.currentThread().getName()+"运行-->"+i);
			if(i == 2){
				System.out.println("线程礼让：");
				Thread.currentThread().yield();//线程礼让
			}
		}
	}
}

public class TestThread2{
	public static void main(String []args){
		MyThread7 my = new MyThread7();
		Thread t1 = new Thread(my,"线程A");
		Thread t2 = new Thread(my,"线程B");
		t1.start();
		t2.start();	
	}
}*/

/*class MyThread7 implements Runnable{
	public void run(){
		for(int i=0; i<50; i++){
			System.out.println(Thread.currentThread().getName()+"-->"+i);
		}
	}
}

public class TestThread2{
	public static void main(String []args){
		MyThread7 my = new MyThread7();
		Thread t = new Thread(my,"线程A");
		t.start();	
		for(int i=0; i<50; i++){
			if(i>25){
				try{
					t.join();
				}catch(Exception e){}
			}
			System.out.println("Main线程运行-->"+i);
		}
	}
}*/

/*
	两者的使用方法不同
	yield	Thread.currentThread().yield();
 	join	t.join();	要捕捉异常
*/

//2,sleep(睡眠)	和	interrupt(中断)
/*class MyThread7 implements Runnable{
	public void run(){
		for(int i=0; i<5; i++){
				try{
					Thread.sleep(500);//达到延迟操作的效果
				}catch(Exception e){}
				System.out.println(Thread.currentThread().getName()+"-->"+i);
		}
	}
}

public class TestThread2{
	public static void main(String []args){
		MyThread7 my = new MyThread7();
		Thread t = new Thread(my,"线程A");
		t.start();	
	}
}*/

class MyThread7 implements Runnable{
	public void run(){
		System.out.println("1,进入run方法");
		try{
					Thread.sleep(10000);
					System.out.println("2,已完成休眠");
		}catch(Exception e){
				System.out.println("3,休眠被终止");
				return;
		}
		System.out.println("4,run方法正常结束");
	}
}

public class TestThread2{
	public static void main(String []args){
		MyThread7 my = new MyThread7();
		Thread t = new Thread(my,"线程A");
		t.start();	
		try{
				Thread.sleep(2000);
		}catch(Exception e){}
		t.interrupt();
	}
}
/*
	休眠多久，即是间隔多久
*/
