如何在java Socket / SSLSocket上设置读取超时？

Question

If I have a connected socket and and it is waiting(blocking) to receive some data from the remote machine but somehow or other, the remote machine loses its connection, how can I make it such that it stops blocking but times out after a certain period of time without receiving any data? I'm using a Scanner object to read data from the socket and a PrintWriter object to write,

// Get InputStream
scanner = new Scanner( clientSocket.getInputStream() );
// Get OutputStream
printWriter = new PrintWriter( clientSocket.getOutputStream(), true );

如果使用套接字，则可以设置超时选项
