Java多线程的介绍及使用

package 多线程;

继承Runable接口，推荐使用

/**
 * 推荐使用Runnable
 */
public class Demo03 implements Runnable {
    @Override
    public void run() {
        for (int i = 0; i < 200; i++) {
            System.out.println(Thread.currentThread().getName()+"当前的数字是"+i);
        }
    }

    public static void main(String[] args) {
        Demo03 demo03 = new Demo03();
        Thread th = new Thread(demo03,"小明");
        Thread th2 = new Thread(demo03,"小化");
        th.start();
        th2.start();
    }
}
···
继承Thread类

package 多线程;

public class Demo01 extends Thread {
@Override
public void run() {
for (int i = 0; i < 200; i++) {
System.out.println(Thread.currentThread().getName()+"当前数字是"+i);
}
}

public static void main(String[] args) {
    Demo01 demo01 = new Demo01();
    demo01.start();
    for (int i = 0; i < 300; i++) {
        System.out.println(Thread.currentThread().getName()+"当前数字是"+i);
    }
}

}
