HW 5: Arrays and Data Structures

One of the first computer games in the 1970's was an adventure game called "Hunt the Wumpus". In this game, you are forced to wander around a maze of caves, hunting the dreaded wumpus (or possible more than one wumpi). When you enter a cave that is adjacent to a wumpus, you will smell its stench. Warned by your nose, you can then throw a hand grenade into an adjacent cave to try to kill the wumpus. Unfortunately, the sound of the explosion will alert any nearby wumpi and set them in motion. The object of the game is to kill all of the wumpi before you run out of grenades (and without getting killed). In addition to wumpi, there is a bottomless pit and giant bats to avoid. Below is a sample execution of the game.

HUNT THE WUMPUS: Your mission is to explore the maze of caves and destroy all of the wumpi (without getting yourself killed). To move to an adjacent cave, enter 'M' and the tunnel number. To toss a grenade into a cave, enter 'T' and the tunnel number.

You have been given the following classes to represent the maze structure and implement the text-based game:,,, and caves.txt. In addition, the javadoc page for is provided.

Part 1: Cave

You are to implement the Cave class, which models a single cave in the maze. Each cave has a name and a number associated with it, and is connected to three other caves through tunnels. By default, a cave is empty (using the enumerated type value CaveContents.EMPTY) but it can be assigned to contain a wumpus (CaveContents.WUMPUS), a swarm of bats (CaveContents.BATS), or a bottomless pit (CaveContents.PIT). In addition, a cave is initially unvisited, but it can be marked as visited.

Be sure to test your Cave class thoroughly.

Part 2: CaveMaze

An incomplete implementation of the CaveMaze class is provided. Currently, it reads in the cave data file (caves.txt) and allows the player to move around the maze. You are to complete the functionality of the game by making the following additions.
