how to kill a thread which is waiting for blocking function call in Java?

I have a thread:

Thread t = new Thread(){
    public void run(){
        ServerSocketConnection scn = (ServerSocketConnection)
                Connector.open("socket://:1234");
        // Wait for a connection.
        SocketConnection sc = (SocketConnection) scn.acceptAndOpen();
       //do other operation
    }
};
t.start();

Lets say no client is connecting to the Server, so this thread will be blocked.Now I want to kill the above thread t? How can I kill it?
