1. 實現Runnable介面 

implements Runnable

1. 重寫run()方法

@Override
public void run(){//TODO}

1. 建立執行緒物件：

Thread thread1 = new Thread(new ImplementsRunnable());

1. 開啟執行緒執行：

thread1.start();

public class ImplementsRunnable implements Runnable{
    public static int num = 0;

    @Override
    public void run() {
        for (int i = 0; i < 10; i++) {
            System.out.println(Thread.currentThread().getName() + ": num = " + num++);
        }
    }
    public static void main(String[] args) {
        Thread thread1 = new Thread(new ImplementsRunnable());
        Thread thread2 = new Thread(new ImplementsRunnable());
        thread1.setName("執行緒1");
        thread2.setName("執行緒2");
        thread1.start();
        thread2.start();
    }
}
