Question
I'm seeing this assignment post for 1 investor, I'm having issues creating it for 2 investors (two accounts). Help Please!
Directions
Points
The files must be called <LiFiUnit4Ch13.java> The files must be called <LiFiUnit4Ch13Inevstor.java> (LiFi = Last Initial First Initial)
Proper coding conventions required the first letter of the class start with a capital letter and the first letter of each additional word start with a capital letter.
Only submit the .java files needed to make the program run. Do not submit the .class files or any other files.

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)
