JAVA homework(netbeans)

In this homework you are going to implement a Room class that has the following private attributes: name : The name of the room ( i.e. bedroom, bathroom, kitchen etc.) size: The size of the room in squaremeters (integer) windowCount: The number of windows in the room (integer) heated: A flag denoting if the room has some heating equipment(boolean) Your class should include appropriate constructors , getters and setters as public. When ,for example,Room r1 with size s, windowCount w, is converted to string and printed out with System.out.println, the text should be as: name [size m^2] with w window with/without heating You are also supposed to implement an Apartment class that contains a name and 4 rooms (namely room1, room2, room3, and room4) as members. The Apartment class should have the following public methods Constructor taking 4 rooms as parameters toString(): prints the name of the apartment and all of the rooms line by line (calling toString() methods of Rooms ) smallestRoom(): returns the smallest room in the market isHeated(): returns true if at least 2 of the rooms are heated, false otherwise getTotalSize(): returns the total size of the apartment (sum of the sizes of the rooms). After implementing Room and Apartment classes you must write a third class (give any name) that only includes a main function. In the main function, create at least 4 arbitrary Room object and create an Apartment object containing 4 of those rooms as members. Print out the apartment and total size of the apartment. Call each method of the apartment class in the main function.
