- Which of the following, can be done, with the help of the this reference?arrow_forward1. Create a properly encapsulated class named Person that has the following: A String instance variable called name. A constructor that takes a String parameter and sets the instance variable. A properly named getter for the instance variable. A correctly overrided equals method which returns true if the name instance variable of the parameter and the reference variable calling the method are equal. (Do not forget the null and class type checks!) Compile your Person class. 2. Create a properly encapsulated class named Employee that inherits from Person and has the following: ● ● ● A String instance variable called office (e.g. "LWH 2222"). A String instance variable called hourlywage (e.g. "$45.15"). A constructor that takes three Strings as parameters for name, office, and hourlyWage and sets the instance variables of both the parent class and the Employee class. An overridden toString method that returns the concatenation of name and hourlyWage instance variables (separated by a…arrow_forwardExplain...........

- Part A Create a class named Apartment that holds an apartment number as aptNumber, number of bedrooms as bedrooms, number of baths as baths, and rent amount as rent. Create a default constructor that accepts no arguments and an overloaded constructor that accepts values for each data field. Also create a get method for each field. Part B Write an application called TestApartments that creates at least five Apartment objects. Then prompt a user to enter a minimum number of bedrooms required, a minimum number of baths required, and a maximum rent the user is willing to pay. Display data for all the Apartment objects that meet the user’s criteria or an appropriate message if no such apartments are available. An example of the program is shown below: Enter minimum number of bedrooms needed >> 2 Enter minimum number of bathrooms needed >> 1.5 Enter maximum rent willing to pay >> 1200 Apartments meeting criteria of at least 2 bedrooms, at least 1.5 baths, and no more than…arrow_forwardOverriding is useful when a method has the same signature and type as a method in the parent class. O a local variable has the same name as an instance variable. O you want to change the return type of a method. O a method has the same signature as another method in the same class.arrow_forward
