Some help with this java code please! Complete the following CheckingAccount class by adding the constructor, getter, setter, and toString

methods as requested. You also need to add the greeting method as explained.

public class CheckingAccount $\{$

private int accountld;

private double balance;

private String firstName;

private String lastName;

$//$Constructor initializes the instance variables of accountld and balance to zero.

$//$ Add setters and getters for all instance variables. For the setters of String variables you can set the

value to String "None" and for numbers for balance and accountld set them to a random value.

$//$toString method is supposed to print the firstName followed by lastName on the same line.

$//$Add a method called Greeting$()$ that prints a welcome message for the customer, the message must

include the fullname of the account owner. This method does not accept input and does not return

anything.
