JAVA并发知识库

1、Java中实现多线程有几种方法？

2、继承Thread类

答：
Thread 类本质上是实现了Runnable接口的一个实例，代表一个线程的实例。启动线程的唯一方法就是通过Thread类的start()实例方法。 start()方法是一个native方法，它将启动一个新线程，并执行run()方法。

public class MyThread extends Thread {
   
   
	public void run() {
   
   
		System.out.println("MyThread.run()");
	}
}
MyThread myThread1 = new MyThread();
myThread1.start();
