介绍有关java的资料 课件 相当一本书籍 里面都是很基础的知识

class twothread implements Runnable {
  twothread() {
    Thread t1 =Thread.currentThread();
    t1.setName("The first main thread");
    System.out.println("The running thread:" + t1);
    Thread t2 = new Thread(this,"the second thread");
    System.out.println("creat another thread");
    t2.start();
    try {
      System.out.println("first thread will sleep");
      //Thread.sleep(4000);
      t1.sleep(4000);
     } catch (InterruptedException e) {
       System.out.println("first thread has wrong");
     }
     System.out.println("first thread exit");
  }

  public void run() {
     try { for (int i=0;i<5;i++) {
        System.out.println("Sleep time for thread 2:"+i);
        Thread.sleep(1000);}
      } catch (InterruptedException e) {
        System.out.println("thread has wrong");
      }
      System.out.println("second thread exit");
  }

  public static void main(String args[]) {
     new twothread();
  }
