Solved-Project 4- Solution

Description

Background

Word has spread about the great work you’ve been doing creating software to predict monster captures. A certain Professor Oak from Pallet Town is particularly impressed with your work, and is interested in enlisting your aid in an exciting new endeavour. He heard that programs written in Java can run on millions of different devices, so he wants you to develop a portable, text­based Pokedex program that his field agents can use in their varying computer systems that are used in many different regions.

Objective

To be the very best, like no one ever was.

Your Assignment

Armed with your newly gained knowledge of Arrays and Objects, your task is to develop a program which makes use of simple but well­structured Pokemon and Pokedex classes in order for field agents to keep track of the strange new Pokemon they encounter on their journies.

Your Pokedex will have the advanced functionality that Professor Oak’s field agents have come to expect: They will be able to:

• add new species of Pokemon to their Pokedex

• list of all the Pokemon that have been stored

• list an individual Pokemon’s statistics

• sort their Pokedex

• The program that you create and submit must contain three files, named exactly as follows: Pokemon.java, Pokedex.java, and

Project4.java, which will hold your main() method. Each of the

.java files and their associated classes are described below:

The Pokemon Class

Your Pokemon class, which is stored in Pokemon.java, defines what constitutes an object of type Pokemon. The class must have the following members:

• Fields for the following attributes:

• • species

• • attack

• • defense

• • speed

• Modifier methods (used in testing, not in menu):

• • public void grow(int boost)

• • • This method increases attack based on the given boost

• • public void harden(int boost)

• • • This method increases defense based on given boost

  • public void haste(int boost)

• • • This method increases speed based on the given boost

• “Getter”/“Setter” methods for each attribute:

• • public String getSpecies()

• • public void setSpecies(String spc)

• • • • Names should consist of one­ word strings ONLY.

• • public int getAttack()

• • public void setAttack(int atk)

• • public int getDefense()

• • public void setDefense(int def)

• • public int getSpeed()

• • public void setSpeed(int spd)

• An appropriate constructor:

• public Pokemon(String species)

• The constructor must initialize all 4 fields of the Pokemon object with the constructor’s parameters:

• • species = species Passed in

• • attack = (Length of species name * 4) + 2

• • defense = (Length of species name * 2) + 7

• • speed = (Length of species name * 3) + 5

The Pokedex Class

The Pokedex class, which is stored in Pokedex.java, will define what constitutes an object of type Pokedex. The Pokedex class must have the following members:

• An array of Pokemon objects, which will hold any pokemon that the user adds to it.

• • You may have any additional fields that may aid the rest of the class’s functionality (strongly recommended). It is recommended to keep a variable in the Pokedex that allows you to keep track of the number of Pokemon you have stored so far.

• • The user will have to input the size of the array

• Member methods (More details on the usage each method are provided later in the project description­ You must have the same method definitions as the ones provided below):

• • public String[] listPokemon()

• • • This method returns an array of Strings containing the names of every Pokemon stored in the Pokedex. The Pokedex class has a field that is an array of Pokemon objects. This method will look at each Pokemon stored in the Pokedex object’s Pokemon array, access the name of the species, and save it into an Array of Strings. The String[] output should be a list containing the names of all Pokemon species currently saved in the Pokedex, with no empty indexes. For example, if your Pokedex holds 20 Pokemon and you have only stored 10, your String[] returned should have a length of 10, not 20. If the Pokedex is currently empty, return null. See example runs for details.

    • public boolean addPokemon(String species)

• • This method takes a String parameter called species and stores it in the Pokedex. It does this by adding it to the next free index in the Pokedex’s Pokemon[] array. Return true if the operation was successful, otherwise return false.

• • • You should check the Pokedex’s Pokemon[] array to see if it already contains the species of Pokemon which you are trying to add (regardless of case differences). If it does, do NOT add the Pokemon to the Pokedex ­ instead, print the word “Duplicate” and return false

• • • You should also design this method so that it does not add the Pokemon if the Pokedex is already at the maximum size. If the Pokedex object’s Pokemon[] array is already full, it should instead print the word “Max” and return false

• • See the sample run for more details.

• public int[] checkStats(String species)

• • This method returns an array of 3 integers containing the attack, defense, and speed of the pokemon specified by a species string argument, in that order.

• • If the given Pokemon is not in the dex, return null. When checking whether the given Pokemon exists, use case­insensitive string comparisons.

• • See sample run for more details.

• public void sortPokemon()

• • This method implements a simple Selection Sort. It will sort the elements in the Pokedex’s Pokemon array alphabetically based on the Pokemon’s species names.

Submission Requirements

• Name the classes described above as Pokemon.java,

Pokedex.java, and Project4.java

• Please zip the 3 files and send them. Please do NOT create a folder.

• Mac: Select all source files ­> right click ­> Compress 3 items

• Windows: Select all source files ­> right click ­> Compressed (zipped) Folder

• Please rename the zipped file such that it is

named project4_ulfid.zip where uflID is the alphanumeric portion of your ufl email account that comes before the @ufl.edu part.

• Submit on time using Canvas

If you submit the files without zipping, your project will not be graded.

If your zip file is not named project4_ulfid.zip, your project will not be graded.

If you do not name the items above exactly as specified, where specified, your project will not be graded.

It is highly recommended that you test your program piece by piece before assembling your final code. You will have a much easier time if you build your program piece by piece rather than trying to write the entire program. Your methods should not differ in any way from the methods given. Using additional prompts, words, abbreviations, etc may result in the grading program taking unnecessary points off and the world’s smallest violin being played for your sorrows.

Please be sure to use the sample output to check your work

Grading

• 100% of your program will be graded on implementing all of the mandatory Class and methods follow the instruction. You are expected to generate proper output (from the methods).
