1、继承 java.lang.Thread 类。

　2、实现Runnable 接口。

class ThreadText extends Thread {
  public void run() {
    for (int a=0; a<10; a++) {
      System.out.println(currentThread().getName() + ":-1:" + a);
    }
  }
}

class RunnableText implements Runnable {
  public void run() {
    for (int a=0; a<10; a++) {
      System.out.println(Thread.currentThread().getName() + ":-2:" + a);
    }
  }
}

public class StartThread {
  public static void main(String[] args) {
    ThreadText tt1 = new ThreadText();
    tt1.start();
    tt1.run();

    RunnableText tt2 = new RunnableText();
    Thread thread = new Thread(tt2);
    Thread thread1 = new Thread(tt2);
    thread.start();
    try {
      thread.join() ;
    } catch (InterruptedException ex) {
      throw new RuntimeException(ex);
    }

    System.out.println("thread1 will be start!");
    thread1.start();
  }
}
