    Default relation between interrupt status and sleep method

    Hi !
    --->My doubt Is on relation ship between sleep method and interrupt status flag.
    --->I am asking this doubt based on below two programmes.
    --->In programme1, I have called sleep method with out clearing interrupt status .Then InterruptedException was thrown.
    --->In programme2 ,I have called sleep method after clearing interrupt status flag using interrupted method.Then InterruptedException was not thrown.
    Is there any relation ship between sleep method and interrupt status flag?
    Does sleep method throws Interrupted exception based on interrupt status flag?
    ---------------------------------------------------------------
    Programme1:
    class even extends Thread
    {
    public void run()
    {
    for(int i=10;i<=20;i=i+2)
    {
    System.out.println(i);
    this.interrupt();
    try
    {
    Thread.sleep(1000);
    }
    catch(InterruptedException ie)
    {
    System.out.println("interrupted");
    }
     
    }
    }
    }
    class interrupt1
    {
    public static void main(String args[])
    {
    even e1=new even();
    e1.start();
    }
    }
    Output:
    10
    interrupted
    12
    interrupted
    14
    interrupted
    16
    interrupted
    18
    interrupted
    20
    Interrupted
    ---------------------------------------------------------------
    Programme2:
    class even extends Thread
    {
    public void run()
    {
    for(int i=10;i<=20;i=i+2)
    {
    System.out.println(i);
    this.interrupt();
    Thread.interrupted();
    try
    {
    Thread.sleep(1000);
    }
    catch(InterruptedException ie)
    {
    System.out.println("interrupted");
    }
     
    }
    }
    }
    class interrupt2
    {
    public static void main(String args[])
    {
    even e1=new even();
    e1.start();
    }
    }
    output:

    Default Re: relation between interrupt status and sleep method

    Please edit you post and properly align the code. nested statements should be indented 3-4 spaces.
    All statements should NOT start in the first column.

    Hi!
    I am a beginner of java.
    Now I am studying multi threading.
    I want to know relationship between sleep and interrupt status flag".
    I have referred so many books before asking this question here.
    But I could not find the relation between sleep and interrupt status flag.
    I need a book which explains such type of depth topics.
    can u suggest such type of java book?
