1. ArrayListOfObjects
Assignment 4:
100 points
due Thurs, Feb 23rd.
Adapt your ArrayOfPokemon code from assignment 2 to use the new Pokemon objects.
When adding a Pokemon, instead of making the user enter all the information, make a menu for
them to pick from the nine (or more) implemented species: (Bulbasaur, Ivysaur, Venusaur,
Charmander, Charmaleon, Charizard, Squirtle, Wartortle, Blastoise).The only thing the user must
choose is the species of Pokemon and if it gets a name.
If they want a name, then the program should ask them to enter one.
Then call the constructor for the chosen Pokemon. For example: Pokemon p = new Bulbasaur();
or Pokemon p = new Squirtle(sName);
Change the Array from assignment 2 to a Java API ArrayList.
For examples on using an ArrayList, see the uploaded sample code ArrayListDemo.java and
slide 40 of ICS211_Lecture09_ListsAndContainers.pdf on Laulima -> Resources -> Week 5.
Also see the Java API website for ArrayList for available methods.
The allowed number of stored Pokemon should still be limited to 6. Don't let the ArrayList keep
growing though it can!
Assignment 2 code is here,Please help me change it to match Assignment 4's requirement.
