Question

using python 3:

Program 14: Class with Private Attribute Collection of Objects: modRoom.py Step 1: Create a class called Room as indicated by the UML shown below: Student -length: integer width: integer -height integer -roomNum: integer -roomType: String -room Capacity: integer <<constructor Room (tmpRoomNum:integer tmpRoomType: String, tmpCapacity:integer tmplength: integer, tmpWidth: integer, tmpHeight: integer) +get Length(): Integer +getWidth(): Integer +getHeight(): Integer +get RoomNum(): Integer +getRoom Type(): String +getRoomCapacity(): Integer tRoomType(): String +set +setRoomCapacity(): Integer +calcArea(): Integer +calcSurfaceArea(): nteger +str( String should return a string containing roomNum roomCapacity, roomArea Step 2: Create a testRoomModule.py file that THOROUGHLY tests your Room class. Make sure to LABEL the output so that it's easy to see what is being tested Step 3: Create another class called RoomRoster as shown by the UML below, and save it into the same modstudent.py file as the Student class: Room Roster -roomCollection: st of room Objects <<constructor>> Room Roster() +add Room (room obj) void +delRoom (roomObj): integer eturns +1 if successful, -1 if unsuccessful +str String +findRoom (roomNum): Room Object or -1 if not there +findRoomsWithCapacity (tmpCapacity integer): List of Room Objects (-1 if none Step 4: Add code to the testRoomModule.py to THOROUGHLY test the RoomRoster class. Make sure to LABEL the output so that it's easy to see what is being tested
