1. 继承Thread类的方式进行实现

public class MyThread extends Thread{
@Override
public void run(){//多线程具体业务逻辑}
}在main方法里面创建子类对象，开启线程
public static void main(String[] args) {MyThread t1 = new MyThread();
MyThread t2 = new MyThread();
t1.setName(”线程1”);
t2.setName(“线程2”);
//开启线程
t1.start();
t2.start();
}

3. 实现Runnable接口的方式进行实现

public class MyRunThread implements Runnable{@Overridepublic void run(){//多线程具体业务逻辑}
}public static void main(String[] args) {MyRunThread mr = new MyRunThread ();Thread t1 = new Thread(mr);
Thread t2 = new Thread(mr);t1.setName(”线程1”);
t2.setName(“线程2”);
t1.start();
t2.start();
}

5. 使用线程池
