线程的两种实现方式
（1）继承Thread类``
/**
* 继承Thread类
*
*/
public class PayThread extends Thread {
@Override
public void run() {
System.out.println("继承Thread");
}
public static void main(String[] args) {
Thread payThread = new PayThread();
payThread.start();
}
}
（2）实现Runnable接口
/**
* 实现Runnable接口
*
*/
public class PayRunnable implements Runnable {
@Override
public void run() {
System.out.println("实现Runnable");
}
public static void main(String[] args) {
Thread payThread = new Thread(new PayRunnable());
payThread.start();
}
