Objective: Your goal is to have a jeroo beautify the Island. Instantiate a jeroo with 8 flowers in its pouch and have the jeroo plant the flowers in the pattern below  Download these beginning-activites

Bank Class

You have a lot of flexibility in creating this class, but here is what it should be able to do

• manage an array list of Accounts that could be any kind of account  private ArrayList<Account>  

Functionality that you *must* implement.

It’s up to you to decide how to implement the functionality below. You will only lose credit if your methods clearly make no sense, have bad variable names/method names.

• add an Account  (of any type)
• remove an account by
  • account id
  • owner (a Person object)

The functionality above ^^ can be implemented in any efficient way that makes sense, but it must be implemented. I am leaving that part up to you!

• Some Specific Required Methods
  • public ArrayList<Person>  topAccountOwners(double cutoff)
    • this method returns an ArrayList of the owners whose accounts have at least cutoff  amount of balance
  • public void nightlyUpdate()
    • this runs through the accounts and if account is a SavingsAccount , then it calls that object’s recordDailyBalance()  method (You are going to have to use instanceOf  and then cast those  accounts to a  SavingsAccount )
  • public  Account topBalance()   ; returns the Account  object with the greatest balance
  • public  Account[] allWithinRange(double min, double max) returns an array of Accounts whose balances range from min  to max , inclusive
  • public  boolean transfer( double amount, int accountIdFrom , int accountIdTo) ;  this method transfers  money from the one account to the other. If the accountIdFrom  does not have enough $$, this method returns false.
  • public  void monthlyUpdate()
    • this runs through the accounts and if
    • account is a SavingsAccount , then it calls that object’s updateInterestPayment() method
  • ** extra credit ArrayList<Account> sortByAmount()  
    •   this method returns an arraylist of Accounts sorted by amount in the account

Shape

Shape Class

Constructor 

• public Shape( int _col)

instance Variables

• protected int color

Accesor Methods

• public abstract double getArea(); //returns the area of the triangle
• public int getColor()
• public void render()  { System.out.println(“rendering shape” ) ; }

Now, let’s refactor our class relationships to represent our new Iheritance Tree

1. refactor all subclasses to reflect new class hierarchy
2. Update our new InteractiveMath class –InteractiveMath3

Create the following class

Circle

Circle
Constructor 

• public Circle( double _radius, int _col)

instance Variables

• double radius
• int color

Accesor Methods

• public double getArea(); //returns the area of the triangle
• public double getCircum() ;// returns the circumference

What should Circle Extend?

Answer!

What relationships exist between super and sub classes?

• How can we use superclasses to improve ourInteractiveMath2 code?
  • To be implemented in  computeNetArea() method
  • How can an element in the Polygon2 ‘ list that  is a RightTriangle2 call the getHypotenuse() method?
    • To be implemented in the new method void printDetails() which should , among other , things print the hypotenuse length for any RightTriangle2’s?
• What is Inherited by subclasses?
  • Constructors?
  • instance variables
  • static variables?

 Next: What if we want to add a Circle Class
