Objectives: At the end of this activity, you should be able to: define classes implement polymorphism and inheritance instantiate an object array apply Exception to all input validations create a Java application for multiple users Procedure: Create a NetBeans project for this activity. The project name should be as follows: o Client (the main class that contains the main method and the implementation of the main menu) o Credit (the class where attributes and methods are defined) The class names to be created are the following: o Client<your_last_name> Ex. ClientBlancoo Credit<your_last_name> Ex. CreditBlanco All class names must be suffixed with your last name. Note that the object to be instantiated in the main method is an object array.For example: CreditBlanco [ ] cb = new CreditBlanco [100]; Compress the NetBeans project into .rar or .zip format and then upload to the link provided in the LMS. Only NetBeans project compressed in .rar or .zip format will be…
Create a class BankAccount with the following private fields:Account_name, title, balance, address. Provide getter and setter fields. Make sure that account balance is greater than 5000/=. The name must and title be alphabets. The address can be alphanumeric.
The BankAccount class models an account of a customer. A BankAccount has the followinginstance variables: A unique account id sequentially assigned when the Bank Account is created. A balance which represents the amount of money in the account A date created which is the date on which the account is created.The following methods are defined in the BankAccount class: Withdraw – subtract money from the balance Deposit – add money to the balance Inquiry on:o Balanceo Account ido Date createdThe SavingsAccount class models a bank account which is meant for long term savingsand earns interest. It inherits all the fields and methods of the BankAccount class. TheSavingsAccount class has an additional instance variable, interest rate. The interest rate is adecimal representing the rate at which the account earns interest. For example, an interestrate of .01 means that the account will earn 1% interest on its balance.The following additional methods are defined in the SavingsAccount…

Create a RobotFriend class. RobotFriend is a new toy just on the market. Copy the starter class and the tester from Codecheck. A RobotFriend has a name and replies to various commands Provide a constructor that takes the name of the RobotFriend as a parameter. Remember that a constructor has the same name as the class. What does the class need to remember? That is the instance variable. Provide the following methods: public String getName() gets the name of this RobotFriend public void setName(String newName) sets a new name for this RobotFriend public String whatDoYouNeed() returns a string consisting of name + " needs a battery charge" where name is the name of this RobotFriend (which was supplied in the constructor) public String doCommand(String whatToDo) returns a string consisting of "Your friend " + name + " does not " + whatToDo where name is the name of this RobotFriend and whatToDo is the parameter

Create class SavingsAccount. Use a variable annualInterestRate to store the annual interest rate for all account holders. Each object of the class contains a private instance variable savingsBalance indicating the amount the saver currently has ondeposit. Provide method calculateMonthlyInterest to calculate the monthly interest by multiplying the savingsBalance by annualInterestRate divided by 12 this interest should be added to savingsBalance. Provide a method modifyInterestRate that sets the annualInterestRate to a new value. Write a program to test class SavingsAccount. Instantiate two savingsAccount objects, saver1 and saver2, with balances of 2000.00 and 3000.00, respectively. Set annualInterestRate to 4%, then calculate the monthly interest and print the new balances for both savers. Then set the annualInterestRate to 5%, calculate the next month’s interest and print the new balances for both savers.
