java例程练习（多线程的两种创建方式）

//接口------推荐
public class Test {
	public static void main(String[] args) {
		
		Runner1 r = new Runner1();
		//r.run();------->不是多线程，只是方法调用
		Thread t = new Thread(r);
		t.start();//必须调用线程类的start()方法
		
		 //也可以这样：
		 //new　Thread(new Runner1()).start();
		 
		
		
		for(int i = 0; i < 100; i++) {
			System.out.println("Main Thread:=========" + i);
		}
	}
}

class Runner1 implements Runnable {
	public void run() {
		for(int i = 0; i < 100; i++) {
			System.out.println("Runner1 :" + i);
		}
	}
}

//继承-----不推荐
public class Test {
	public static void main(String[] args) {
		Runner1 r = new Runner1();
		r.start();
		
		for(int i = 0; i < 100; i++) {
			System.out.println("Main Thread:=========" + i);
		}
	}

}


class Runner1  extends Thread {
	public void run() {
		for(int i = 0; i < 100; i++) {
			System.out.println("Runner1 :" + i);
		}
	}
}
