java多线程

线程两种方式：

1.extends Thread

package study01;

public class ThreadTestExtends extends Thread{
	@Override
	public void run() {
		for(int i = 0; i < 10; i++) {
			System.out.println(Thread.currentThread().getName() + "   " + i);
			try {
				Thread.sleep(1000);
				
			} catch (InterruptedException e) {
				e.printStackTrace();
			}
		}
	}
}

2.implements Runnable

package study01;
//is a 
public class ThreadTest implements Runnable{

	@Override
	public void run() {
		for(int i = 0; i < 10; i++) {
			System.out.println(i + Thread.currentThread().getName());
			try {
				Thread.sleep(1000);
				
			} catch (InterruptedException e) {
				e.printStackTrace();
			}
		}
	}

}

3.启动线程的方式

package study01;

public class Yunxing {
	public static void main(String[] args) {
		//来自继承的线程启动方式
		System.out.println(Thread.currentThread().getName());	
		ThreadTestExtends t1 = new ThreadTestExtends();
		t1.start();
		ThreadTestExtends t2 = new ThreadTestExtends();
		t2.start();
		
		//来自实现接口的线程的启动方式
		Thread t3 = new Thread(new ThreadTest());
		t3.start();
		
	}
	
}
