Java--Threading

Two ways to create thread 1, extends thread this class. 2, implements runnable this interface.

Set Daemon (); Create a background process; Tt.join ("a") means that a thread is released after it is added to the TT (a) MS;

Advantages of using runnable:

Optimize the single inheritance of Java language;

Suitable for multiple threads using the same resource situation;

Train ticket window A total of 100 tickets, with the threading simulation;

Usage:

Class threaddemo{public    static void Main (string[] args)     {        testthread tt=new  testthread ();//enable multiple threads, Multi-threaded shared resources;        new Thread (TT). Start ();         New Thread (TT). Start ();         New Thread (TT). Start ();         New Thread (TT). Start ();     }} Class Testthread implements runnable{    int tickets=100;     public void Run ()    {while        (true)        {            //system.out.println ("Run ():" +thread.currentthread (). GetName ());            while (tickets-->0)                System.out.println (Thread.CurrentThread (). GetName () + "is sailing ticket" + tickets--);        }    }}

　　

Class threaddemo{public    static void Main (string[] args)     {        new Testthread (). Start ();  Enable multiple threads, each thread resource independent;        new Testthread (). Start ();        New Testthread (). Start ();        New Testthread (). Start ();                 /*testthread tt=new testthread ();        Tt.start ();        Tt.start ();        Tt.start ();        Tt.start (); */    }}class testthread extends thread{    int tickets=100;     public void Run ()    {while        (true)        {            //system.out.println ("Run ():" +thread.currentthread (). GetName ());            while (tickets-->0)                System.out.println (Thread.CurrentThread (). GetName () + "is sailing ticket" + tickets--);        }    }}
