Basic Requirements
Write a program that tracks an investments for 2 person based on the input of an interest
rate. The initial balance should be $2,000, and $4,000. The interest should be added to the
balance and output in table format as shown in the supplied sample. LiFiUnit4Ch13.java
o Instantiate an investor1 object using a two parameter constructor
passing the account number 1001 and the initial balance of $2,000
o Instantiate an investor2 object using a two parameter constructor
passing the account number 2001 and the initial balance of $4,000
o Get input for interest rate (in the format .08 for 8%) 45% Use class variable to set interest rate
o Output header as per sample showing interest rate
o Print the table using a for loop displaying the current month and calling: addInterest() to add the monthly interest for each iteration getBalance() to display the current balance (See sample) Output results for 15 months.
o Print the interest earned as shown in the sample for each investor
utilizing a printf statement. Don’t hard code the interest earned, or
interest rate.
Sample output is provided below. Be sure to mimic it exactly except for values will
change based on the interest rate entered.
LiFiUnit4Ch13Investor.java
o All variables should be declared private.
o Declare a class variable called interestRate (This will hold the annual
interest rate)
o Declare a constant called ACCOUNT_NUMBER
o Declare an instance variable called balance
o Provide a class method that will be used to set the annual interest rate
o Provide a two parameter constructor to initialize the constant account
number and balance
o Provide an addInterest() method to update the balance based on the
interestRate entered in the driver. Add the interest using (balance * interestRate / 12) 45% NOTE: Complete your activity and submit it by clicking “Submit Assignment”
