It would be like reading from stdin, except the Java applet would be reading
from a socket. The java socket or NetworkClient class returns whatever it
reads as a byte (or char ?) array, which you would need to tokenize and
parse out into the appropriate number of chars and ints. This is easy to do
using a class like DataInputStream. Of course you would need to know the
exact sequence, number and format of chars and ints the server sends out.
