Multi-class application


Rate this product

Create a multi-class application to report on monster attacks. You will need a class that represents a monster attack, one that aggregates monster attacks by keeping track of an array, and a driver class.

Part A, 40 pts

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, 40 pts

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, 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.

Part C, 20 pts

Create a MonitorDriver class. This class should be the only one with a main() method. 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.
