    Explanation:

    import java. util. LinkedList;

    public class Threadexample

    {

    public static void main (String[] args)

    throws InterruptedException

    {

    final PC pc = new PC ();

    Thread t1 = new Thread (new Runnable ()

    {

    public void run ()

    {

    try

    {

    pc. produce ();

    }

    catch (InterruptedException e)

    {

    e. printStackTrace ();

    }

    }

    });

    Thread t2 = new Thread (new Runnable ()

    {

    public void run ()

    {

    try

    {

    pc. consume ();

    }

    catch (InterruptedException e)

    {

    e. printStackTrace ();

    }

    }

    });

    t1. start ();

    t2. start ();

    t1. join ();

    t2. join ();

    }

    public static class PC

    {

    LinkedList list = new LinkedList ();

    int capacity = 2;

    public void produce () throws InterruptedException

    {

    int value = 0;

    while (true)

    {

    synchronized (this)

    {

    while (list. size () = =capacity)

    wait ();

    System. out. println ("Producer produced-"

    + value);

    list. add (value++);

    notify ();

    Thread. sleep (1000);

    }

    }

    }

    public void consume () throws InterruptedException

    {

    while (true)

    {

    synchronized (this)

    {

    while (list. size () = =0)

    wait ();

    int val = list. removeFirst ();

    System. out. println ("Consumer consumed-"

    + val);

    notify ();

    Thread. sleep (1000);

    }

    }

    }

    }

    }
