JAVA

We will play a game of Improved Artillery. (DO the code based on the following dotted line) In this game, you will have two tanks. Each tank will start a random distance apart.(Should be random) Each tank will take turns firing at the other until one has been eliminated. You will need to create classes for the tank, the game and the main. The tank class should have a method to fire and to take damage as well as a method to report the hit points left. It does not have to move. The game class should contain two instances of the tank class as well as any other variables needed to play the game. The game class will call the fire method from one tank and pass it on to the other tank as damage. You will also need a method in the game class to decide if one tank has been eliminated. You will need additional methods in the game class to play a round and to play the game.
