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);
}
}
}
[java]
//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);
}
}
}
