Hi,

Iam working on creating an audio player applet.

I face some difficulties in multithreading in java. The problem i need
to solve is
explained below,

There are three threads in the player.
1) Master Thread
2) Buffer Thread
3) Play Thread

The master thread should control the other two threads. So Master
thread should
communicate to the Bufffer thread and wait for a response. As soon as
it gets the
response from the Buffer Thread, the master thread should communicate
to the Play thread.
After playing the data, the play thread should send back a message to
the master thread.
Till this message is recieved the master thread should wait.

So the question i have is "How to communicate between threads? How can
we make a thread
wait for other threads response?"

sample code, link Or help in any form is highly appreciated.

Thanks in advance

Does it have to run on pre-1.5 versions of Java?

If not, look at java.util.concurrent, especially the blocking queues.
They seem ideal for the message passing model of thread communication,
and you expressed your problem in terms of message passing.
