Question

A. Create a BankAccount class.

We want to be able to create a new bank account, make deposits and withdrawals, and check the balance. Each bank account created should receive a unique account id, numbered sequentially 1001, 1002, 1003, and so on. We should be able to change the name on the account. We should also be able to retrieve the account id and the name on the account.

Provide a constructor that takes a name for the account as a parameter. Remember that a constructor has the same name as the class. The constructor should initialize all of the instance variables.

What does the class need to remember? Those are the instance variables. There should be three.

Provide the following methods:

public double getID() gets the account id of this BankAccount

public double getBalance() gets the balance of this BankAccount

public String getName() gets the name of this BankAccount

public void setName(String newName) sets a new name for this BankAccount

public void deposit(double amount) deposits an amount into this BankAccount

public void withdraw(double amount) withdraws an amount from this BankAccount

The next step is to write stubs for all the methods.

# B - RobotFriend

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.
