I am done with this assignment think god, and was wondering if someone could please check it so I can make sure there are no errors, it seems like I work hard on these programs but always doing something wrong. I am doing this course online so I have a hard time communicating with the instructor. I think my equals to methods might be wrong but, they seem to have no error when running the program and the program is 100% done. Please take the time to look over it, and thank you so much for your time.
Assignment: About the first class Create a class named RoomDimension that has two fields: one for the length of the room and another for the width. The RoomDimension class should have two constructors: one with no parameters (a default) and one with two parameters. The class should have all of the appropriate get and set methods, a method that returns the area of the room, a toString method that will allow us to print the length, width and area of the room and an equals method to compare room dimensions.
About the second class Create another class named RoomCarpet that has two fields: one is a RoomDimension object and the other is a field that holds the cost of carpet per square foot. The class should have two constructors: one with no parameters and one with the two field parameters (RoomDimension and double). The class should have a get and set method for each field, a method that returns the total cost of carpeting the room, a toString method that will print all of the room information (length, width, area) and cost of the carpet per square foot and the total cost to carpet the room. (Dollar amounts should be displayed with two decimal places.), and an equals method that compares room dimensions and carpet cost.
About the application program Write an application program that contains one RoomDimension object and one RoomCarpet object. The program should allow the user to enter the length and width of the room and the cost of the carpet per square foot. The program should instantiate both objects and use a simple System.out.println statement to print all of the information about the RoomCarpet object.
