PLEASE USE THE FOLLOWING HERO CLASS TO COMPLETE THE QUESTION.

Your task is to create a GUI application that allows a user to create a group of Hero objects. Your group may be a small band of two or three Heroes or it may consist of thousands (think Lord of the Rings or the Marvel Cinematic Universe here).

You have been given the compiled version of the class encapsulating a Hero and you have also been given the specification. Your job is to create a GUI application that allows the user to create an ArrayList of Hero objects. Your GUI should allow the following operations on your Hero list:

? Add Hero objects to the list your list should start out with zero Heroes. You should be able to add Hero objects by reading in from a text file or by adding them individually through the GUI.

? Delete Hero objects from the list you can delete by index number, by hero name or both

? Determine the Hero object with the highest energy level (i.e., the healthiest)

? Cast a spell of heal all that adds a random number of energy points (say between 1 and 50) to all living Heroes.

? Remove all perished (i.e., non?living) Heroes from the list

? Determine the total and average energy points of the entire group of Heroes

? Determine if a particular Hero is in the list search by name

? Write the current Hero list out to a new file
