线程创建的两种方式

创建线程的两种方式：

    1.继承Thread并重写方法，在run方法中定义线程要执行的任务

    

class MyThread extends Thread {
	public void run() {
		for(int i=0;i<1000;i++) {
			System.out.println("who are you ");
		}
	}
}

public class ThreadDemo1 {
	public static void main(String[] args) {
		Thread t1=new MyThread();

		t1.start();
	
	}
}

    2.实现Runable接口并重写run方法

class MyRunnable implements Runnable{
	public void run() {
		for(int i=0;i<1000;i++) {
			System.out.println("I'm a fool");
		}
	}
}

public class ThreadDemo {
	  	public static void main(String[] args) {
		Runnable r1 =new MyRunnable();		
		Thread t1 = new Thread(r1);		
		t1.start();	
	  }	
}

3.两种方式的匿名内部类

public class ThreadDemo3 {
	public static void main(String[] args) {
		
	//使用直接继承线程方式
	Thread t1 = new Thread() {
		public void run() {
			for(int i=0;i<1000;i++) {
				System.out.println("who are you ");
			}
		}	
	};
	t1.start();
			
	//使用实现Runnable接口方式
	Runnable r2= new Runnable() {
		public void run() {
			for(int i=0;i<1000;i++) {
				System.out.println("I'm a fool");
			}
		}	
	};
	Thread t2=new Thread(r2);
	t2.start();
	}	
}
