plz asap java 1- Based on the UML shown below, Implement in Java the following inheritance hierarchy (theclasses' description comes next):Disk- title: String- playTime: int // in minutes+ Disk(title: String, playTime: int)+ getTitle(): String+ getPlayTime(): int+ toString(): String4AudioVideodirector: Stringartist: String- tracksList: java.util.ArrayList- description: String+ Video(director: String, description:+ Audio(artist: String, title: String,playTime: int)String, title: String, playTime: int)+ getArtitst(): String+ getDirector(): String+ getTracksList()+ getDescription(): String+ addTrack(name: String): void+ toString(): String+ removeTrack(name: String): void+ toString(): StringA. Disk class is characterized by a String attributes title and an integer playTime. This class has:A constructor that initializes all the attributes.The getter and setter methods for the attributes.A toString() method that returns each data field at a line in the form:"Title: " + title + "
Play time: " + playTime;B. Audio class inherits the class Disk. It has a String artist and an array list tracksList. This classhas:●A constructor that initializes all attributes in which tracks List attribute has to be created.The getter methods and setters for the attributes..•addTrack method that takes as parameter the name of the track to be added to the array.removeTrack method that takes as parameter the name of the track to be deleted from the array.A toString() method that overrides the toString() method in the Disk class by adding the datafields of the Audio class in the same form.C. Video class inherits the class Disk. It has as attributes two Strings director and description. Thisclass has:A constructor that initializes all attributes.A toString() method that overrides the toString() method in the Disk class by adding the datafields of the Video class in the same form.Create a test program for the classes shown in part 1. Assume that all the classes are implementedand you can use all their methods.a.Create an array of 8 disks with 4 disks of type Audio created at even indices and 4 disks oftype Video created at odd indices. e program will prompt the user to fill all the attributes.b. Write the code that prompts the user to enter the number of tracks to be added to each audiodisk created in the array. Then, the program will prompt the user to enter the name of eachtrack as a String.C. Write the code that displays the detailed information about each disk.d. Prompt the user to enter a title as a String. Then, display whether the title is found amongthe disks in the array.e. Write the code that displays a message (e.g. Disk 0 has to be burned.) if the audio diskcontains less than 4 tracks.solve this only and thanks
