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();
} }
