Make GUI of Colossal cave adventure game in java

You should improve both the game's play and its implementation. Some possible enhancements include, but are not limited to, the following:

interface specifications for return types and formal parameters. Fix this. (Improves implementation, but not play)

Refactor the user interface toi be I18N capable (improves both).

Save and restore the game state on request (improves both).

Change the user interface to be a GUI (improves play, but not implementation).

Extend the game by at least 4 rooms and their associated items. The extension must implement unique behavior of the items and rooms. For example, catching the bird, having appropriate rooms be lit or dark based on the lamp's state, implementing at least one magic word (improves play, but not implementation).

Other extension negotiated prior to starting work; call me--initiative is wonderful. I encourage it. You get to influence what "success" means when you carve out your own improvement.
