Q4) Write a Java class that represent a building. The building has a number of appartments for rent, some are normal and some are delux. The delux appartments are \%20 more expensive than the normal ones. Here is the UML diagram: As shown in the UML diagram, write the class Building that has the attributes: - apts: Total number of appartments in the building. - normal: The number of rented normal appartments in the building. - delux: The number of rented delux appartments in the building. - rent: The monthly rent of a normal appartment. The methods of this class are: - setApts(int apts): void. Sets the value of the attribute apts (since its private) - howManyRented():int. Returns how many appartments are rented. - rentApt(int n, String type):boolean. This method receives an integer n which is the number of appartments we like to rent and their type. Based on the value of type you should increase occupied normal or delux appartments accordingly. But first, you must check if you have n appartments available to rent, If you do then rent the appartments and reurn true, else, return false. - printInfo():void. print all information about the building in an organized manner. After writing class building, write a java class testBuilding to test your building class. In this class you should: 1. Declare an object b of class Building. 2. Read two building attributes: apts and rent from the user. No need to read normal and delux appartments numbers because they start as zero. 3. Ask the user how many delux appartments he would like to rent. If there is availability rent them and display a message stating that n appartments were rented. If not you should display the message "Requested number of appartments exceeds availability" 4. Ask the user how many normal appartments he would like to rent. If there is availability rent them and display a message stating that n appartments were rented. If not you should display the message "Requested number of appartments exceeds availability" 5. Print the building Information. 6. Feel free to try creating additional building objects, read their data and manipulate them. 7. exit. Sample Run 1 Please enter Number of Appartments and rent amount :50 2000 How many delux appartments would you like to rent? 20 20 delux Appartments have been rented How many normal appartments would you like to rent? 15 15 normal Appartments have been rented ================== Building Info ========================== The Building has 50 appartment. Only 35 have been rented. 15 normal appartments with rent =2000.0 SR per month. And 20 delux appartments with rent 2400.0 SR per month Sample Run 2 Enter number of appartments and rent amount :100 10000 How many delux appartments would you like to rent? 70 70 delux Appartments have been rented How many normal appartments would you like to rent? 40 Requested number of appartments exceeds availability The Building has 100 appartment. Only 70 have been rented. 0 normal appartments with rent =10000.0 SR per month. And 70 delux appartments with rent 12000.0 SR per month
