Question

Complete the Monster Attack project by doing the following:

In place of the driver used in homework 2, add a menu with a loop and switch. The user must be able to add attacks, get a report on existing attacks, sve a file, retrieve a file, and clear the list as many times as she wants in any order she wants.

Replace the array of MonsterAttacks with an ArrayList of MonsterAttacks. This will require changes in several methods. You will need to be able to handle any number of MonsterAttacks the user chooses to input.

Add a method to AttackMonitor that saves the list of attacks to a comma separated values file. Iterate through the list, and for each attack, get each field using the getters from MonsterAttack. Write each value to the file, following each one except the last with a comma. Save the date as a single String in the format MM/DD/YYYY. After you have written out all the data for one attack, write out a newline. Add an item to the main menu that calls this method.

Add a method that clears the list of monster attacks, then uses a Scanner to read data from a .csv file, uses it to instantiate MonsterAttack objects, and adds the attacks to the list. This method must be able to read the files you write out in the method described above. You will need to use String's split() method here. Add an item to the main menu that calls this method. Make sure you can input attack data, save to a file, quit the program, start the program again, read your output file, and show the data from the file.

this is in java code

This was part 1 to code the first part: Please help me asap

Part A

Create a MonsterAttack class. MonsterAttack has the following private data variables. Think about the correct data type to use for each variable:

monsterName (eg Godzilla)

attackLocation (eg Tokyo)

damagesInMillionUSD (eg 123.45)

date (eg October 27, 1954, OK to use the Java Date class)

Create whatever constructors, getters, and setters you need. Be sure to write a reasonable toString().

Part B

Create an AttackMonitor class. AttackMonitor contains an array of Monster attacks and has methods to generate reports on the attacks. It should include at least these methods:

reportAttacks() creates an array of five attacks, takes user input using a Scanner from System.in, creates the attacks (instances of MonsterAttack), and adds the attacks to the array.

showAttacks() iterates through the array and prints out the result of running the toString() of each attack.

showDamages() calculates and prints the total amount of damages for all attacks and the mean damages

showMonsters() shows the names of all monsters involved in the attacks and the number of attacks for each monster (ie: "Godzilla, 3 attack(s); Bigfoot, 1 attack(s); Yeti: 1 attack(s)). Since we may discover new monsters after compile time, you must find the names using a getter in MonsterAttack. Don't hard- code the monster names.

findEarliestAttack() prints out the to String() of the earliest MonsterAttack in the array.

A menu method that offers the user the opportunity to run any of the methods listed above or to quit. The menu must be contained in a loop with a swtich statement, as shown in several lecture examples.. The user can do any of the above tasks in any order, as many times as she wants to.

Part C

Write a main() method for AttackMonitor. Think about what it needs to do to show that the other classes work correctly. The driver should only call methods from AttackMonitor, not methods from MonsterAttack.

what else do you need ? i Have provided with all the info just make the adjustments from what its askinf at first to the code I posted
