Need to make a java program that uses a GUI to simulate a battle between the player and an enemy. Basically you will choose a class, and then enter the arena to fight the enemy. If you win you get a bunch of gold, and if you lose you get a small amount of gold. You can use this gold to buy weapons or items to equip to your character that make you stronger. Once you've bought items you should be allowed to fight the enemy again until you beat the enemy and win the game.
