本文通过一个Java多线程程序示例介绍了如何创建和启动线程，展示了线程的基本属性获取方法，并演示了线程休眠的使用。同时，程序还展示了如何通过继承Thread类和实现Runnable接口来定义线程的行为。

public class iphxer
{
    @SuppressWarnings("static-access")
    public static void main (String s[])
    {
        System.out.println("java");
        new Thread(new B("java0")).start();
        new Thread(new B("<span style="font-family:Arial, Helvetica, sans-serif;">java</span>1")).start();
        new Thread(new B("java2")).start();
        new Thread(new B("java3")).start();
        try
        {
            Thread.sleep(5000);
        }
        catch(InterruptedException e)
        {
            e.printStackTrace();
        }
        Thread current = Thread.currentThread();
        System.out.println(current.getPriority());
        System.out.println(current.getName());
        System.out.println(current.activeCount());
        System.out.println(current.getId());
        System.out.println(current.getThreadGroup());
        System.out.println(current.getStackTrace());
        System.out.println(current.hashCode());
        System.out.println(current.toString());
    }
}

class B implements Runnable
{
    private int num=0;
    private String name;
    public B(String s)
    {
        this.name = s;
    }
    public void run()
    {
        System.out.println(this.name);
        try
        {
            Thread.sleep(1000);
        }
        catch (InterruptedException e)
        {
            e.printStackTrace();
        }
    }
}
