Write an application in java that tracks information about monster attacks.

Important: use JOptionPane I/O, not Scanners and System.out, for this lab.

For this lab you will create a MonsterAttack class that represents one monster attack, an AttackMonitor class that aggregates data about attacks, and an MonsterAttackDriver class that instantiates an AttackMonitor.

One of the key functions of AttackMonitor is to read and write data using a text file, but you will complete this part in a future lab. Note that nearly all the methods in AttackMonitor and MonsterAttack will be instance, not static, methods.

Part I - MonsterAttack class

Each object of this class represents information about a single attack. The data on each attack includes an integer attack id, three ints representing the day of the month, the month, and the year of the attack, the name of the monster involved (assume that each attack involves only one monster), the location of the attack (String), and the name of the person reporting the attack (String).

MonsterAttack needs a constructor that sets all the instance fields listed above using its parameters. It should take the three components of the date as a single String in the format MM/DD/YYYY (eg, 01/31/2010). Use String's split method to split this String on the slashes, parse the resulting Strings to ints, and use them to set the values of the month, day, and year.

Monster attack also needs getters and setters for all the data fields and a toString() that uses the instance data to create and return a String similar to this: "Attack # 125: Godzilla attacked Tokyo on 6/25/2009. Reported by Kyohei Yamane."

Part II - AttackMonitor

Create an AttackMonitor class that keeps track of the MonsterAttack objects. It should contain an array list (not an array) of MonsterAttacks and an instance method called monitor() with a menu that allows the user to choose to quit or to do any of the tasks listed below, which must all be implemented in separate methods.

After doing any of these tasks, the program should return to the menu, so that the user can continue working on any series of tasks until he/she chooses to quit. Write instance, not static, methods to do each of the following:

Input information on a MonsterAttack. You will have to parse some of the input Strings to ints. When you have all the data, call the MonsterAttack constructor, using the input data, and add the new attack to the list of attacks.

Create a MonsterAttack using method parameters and add it to the list. In other words, this method will take parameters for the data fields, rather than taking them as user input.

Show the current list of attacks by iterating through the list, calling the toString() of each attack, and outputting the result to a dialog box. Write this method so that the program does not crash if the list is empty.

Choose an attack from the array list and delete it. The easiest way to do this is to call the method that shows the information, then ask the user for the id number of the attack to delete. Use linear search to find the attack with that id and delete it. The id number may not be the same as the index in the list. Make sure the application does not crash if the user enters an id that does not appear in the list.

Part III: MonsterAttackDriver

The driver class should instantiate an AttackMonitor and call its monitor() method.

In order to make the application easier to test, the driver should provide hard coded data on three attacks. Use the data to create the three attacks and add them to the list in the monitor.
