There are many different kinds of investments, including stocks, mutual funds, real estate, and bank accounts. There are two kinds of bank accounts: checking and savings. Design an abstract Investment class that includes a name attribute, a value attribute ( double ), and a getter method, getValue(). The Investment class, being abstract , cannot be instantiated. Design subclasses: Stocks, MutualFunds, RealEstate , and BankAccount . The attributes of Stocks are name , pricePerShare , numberOfSharesOwned , and dividend (a percent of the investment paid annually). The attributes of MutualFunds are: name , pricePerShare , and numberOfSharesOwned . The attributes of RealEstate are: name, addressOf Property , purchasePrice , and currentAssessedValue. BankAccount is an abstract class that extends Investment . The name fi eld holds the banks name. An additional attribute accountNumber ( String ) represents an account number

BankAccount has two subclasses: SavingsAccount and CheckingAccount . A SavingsAccount object has an annual interest rate paid quarterly. SavingsAccount has a method addInterest() that adjusts the balance of the account. A CheckingAccount is-a BankAccount with a minimum balance, a penalty if the balance goes below the minimum in any month, and an annual interest rate (paid monthly) on the money in excess of the minimum balance. Include method addInterest() , which adds one months interest to the balance, and a method checkBalance() , which adjusts the balance if the balance falls below the minimum. The classes are simple. Each class has a default constructor that sets each instance variable to the empty string or zero, whichever is appropriate, and a second constructor that sets the class attributes, including value . Each class that is not abstract should also include a method displayData() that prints all the information of a particular investment, properly labeled.

A portfolio is an array of Investment references. Implement a Portfolio class that

also includes a getNetValue() method. This method returns the sum of the values of all investments referenced by portfolio . Interactively, create a portfolio with at least six investments, including stocks, mutual funds, real estate, and a bank account. Display the data for each investment along with the net value of all investments.
