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

//Define our simple threads.They will pause for a short time
//and then print out their names and delay times

class TestThread extends Thread {
    private String whoami;
    private int delay;

    //Our constructor to store the name (whoami)
    //and time to sleep (delay)

    public TestThread(String s, int d) { whoami = s; delay = d; }

    //Run - the thread method similar to main()
    //When run is finished, the thread dies.
    //Run is called from the start() method of Thread

    public void run() {
        //Try to sleep for the specified time
        try { sleep(delay); }
        catch(InterruptedException e) {}
        //Now print out our name
        System.out.println("Hello World!"+whoami+"="+delay); }
    }
