- Is there a different way of doing this problem? Question: Create a class AccessPoint with the following attributes: x - a double representing the x coordinate y - a double representing the y coordinate range - an integer representing the coverage radius status - On or Off Add constructors. The default constructor should create an access point object at position (0.0, 0.0), coverage radius 0, and Off. Add accessor and mutator functions: getX, getY, getRange, getStatus, setX, setY, setRange and setStatus. Also, add a set function that sets the location coordinates and the range. Add the following member functions: move and coverageArea. Add a function overlap that checks if two access points overlap their coverage and returns true if they overlap. Add a function signalStrength that returns the wireless signal strength as a percentage. The signal strength decreases as one moves away from the access point location. Test your class by writing a main function that creates five access…Use the code provided copied to a new file named compulsory_task_1.py: 1. Add another method in the Course class that prints the head office location: Woodstock, Cape Town2. Create a subclass of the Course class named OOPCourse3.

Create a method in the subclass named "trainer_details" that prints what the course is about and the name of the trainer by using the description and trainer attributes.5. Create a method in the subclass named "show_course_id" that prints the ID number of the course: #123456.

- Solve this question using java language you have to read the information from a file then print them in a file please read the instructour carefully, also look at the attach image to help you to solve it. pecificationsWhat You Must ImplementYou must define a class named MediaRental that implements the MediaRentalInt interface functionality(index A). You must define classes that support the functionality specified by the interface. The followingspecifications are associated with the project:1. Define a class named MediaRental. Feel free to add any instance variables you understand are needed or anyprivate methods. Do not add any public methods (beyond the ones specified in the MediaRentalInt interface).2. The media rental system keeps track of customers and media (movies ,music albums and games). A customerhas a name, address as string , a plan and two lists. One list represent the media the customer is interested inreceiving and the second one represents the media already received…In order to provide a user interface, we need to provide a layer on top of the ParkingOffice class that will accept commands and send them on.

Create an instance method called count that takes a single parameter called dataFile (representing the path to a text file) and uses a Map of Strings to count how many times each word occurs in dataFile. The counts should be stored in an instance variable called wordCounter. Create an instance method called write that takes a single parameter called outputFile (representing the path to a text file) and writes the contents of wordCounter to the file pointed to by outputFile. The output file should be overwritten if it already exists, and created if it does not exist. Create a separate class called Application that contains a main method which illustrates the use of DuplicateCounter by calling both the remove and write methods. Your input file must be called problem2.txt and your output file must be called unique_word_counts.tx
