DATA FOR BUTTON APPLICATION IN JAVA:

ButtonProxy.java
  used to model Proxy pattern. Only establishes connection with Server
  if need be. left click always goes to server to get coordinate
  information while right click only goes if button has not been right
  clicked before

ButtonServer.java
  server used for sending results of intense computations back to
  remote client, in this case, the intense computation consists of the
  following:

    left click- engages retrieval of coordinate information, along
    with which button has been clicked

    right click- first time right click does a simple addition on the
    coordinates and label of button and returns computed value to
    proxy. subsequent right clicks on buttons with the same label will
    give the computed result


ButtonFlyweight.java
  implements the flyweight factory pattern by creating a grid of
  Buttons which listens for right and left mouse clicks. Information is
  sent to the button proxy class for information retrieval.
