1. 繼承Thread類的方式進行實現

public class MyThread extends Thread{
@Override
public void run(){//多線程具體業務邏輯}
}在main方法里面創建子類對象，開啟線程
public static void main(String[] args) {MyThread t1 = new MyThread();
MyThread t2 = new MyThread();
t1.setName(”線程1”);
t2.setName(“線程2”);
//開啟線程
t1.start();
t2.start();
}

3. 實現Runnable接口的方式進行實現

public class MyRunThread implements Runnable{@Overridepublic void run(){//多線程具體業務邏輯}
}public static void main(String[] args) {MyRunThread mr = new MyRunThread ();Thread t1 = new Thread(mr);
Thread t2 = new Thread(mr);t1.setName(”線程1”);
t2.setName(“線程2”);
t1.start();
t2.start();
}

5. 使用線程池
