线程实现有两种方法:
1.写一个类来继承Thread类,然后复写run()方法。
public class HelloThread extends Thread { public void run() { System.out.println("Hello from a thread!"); } public static void main(String args[]) { (new HelloThread()).start(); } }
2.写一个类实现Runnable接口,然后复写run()方法。
public classHelloRunnable implements Runnable { public void run() { System.out.println("Hello from athread!"); } public static void main(String args[]) { (new Thread(newHelloRunnable())).start(); } }
