1- Based on the UML shown below, Implement in Java the following inheritance hierarchy (the classes' description comes next): Disk -title: String -playTime: int // in minutes + Disk(title: String, playTime: int) + getTitle(): String + getPlayTime(): int + toString(): String 4 Audio Video -artist: String - director: String - tracksList: java.util.ArrayList - description: String + Audio(artist: String, title: String, play Time: int) + Video(director: String, description: String, title: String, playTime: int) + getArtitst(): String + getDirector(): String + getTracksList() + getDescription(): String + toString(): String + addTrack(name: String): void + removeTrack(name: String): void +toString(): String A. 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 to String() method that returns each data field at a line in the form: "Title: " + title + "\nPlay time: " + playTime;

In Java, implement abstract classes and interface in the grading system. Include three different implementation methods in solving the grade. Kindly follow the example of coding below (abstract class should be included): Example: Enter Prelim: 30 Enter Midterm: 30 Enter Endterm: 40 --------------------- Formula: (Prelim+ Midterm + Endterm)/3 ------------------------------

Computer Science There are clearly some similarities in the implementations of Taxi and Shuttle that suggest use of inheritance to represent them. Introducing inheritance is the primary task of this assessment. -The Ezcab class, The Ezcab class maintains separate lists of taxis and shuttles and destinations with destination fares (you can hardcode destination fares). It has a lookup method that searches for a taxi/shuttle with a given ID. -The Taxi and Shuttle classes share some common attributes – location and destination. They also have some common methods – getLocation, getDestination, getStatus and setDestination. -Vehicle is the superclass of both Taxi and Shuttle. This class involves placing the common fields and methods into Vehicle and removing them from Taxi and Shuttle. -Modify Taxi and Shuttle class to indicate that it is a subclass of Vehicle. You can keep the id field in Vehicle class and getId,SetId methods. -Arrange for Taxi's constructor to call the constructor of…

Java does not support multiple inheritance, but some of the abilities of multiple inheritance are available by Java does not support multiple inheritance, but some of the abilities of multiple inheritance are available by overriding parent class methods creating aliases importing classes using public rather than protected or private modifiers implementing interfaces
Write a Java program with the following: An abstract superclass with one abstract method that sorts an ArrayList object in ascending order. A subclass that overrides the abstract method in the superclass. A class ACTIVITY that contains main(). in main(): Initialized an array of strings with at least ten(10) elements and use this array as the elements of the ArrayList object. Create an object of the subclass and use this object to sort the ArrayList object. Display the sorted list.
Write an java inheritance hierarchy for classes Quadrilateral, Trapezoid, Parallelogram, Rectangle and Square. Use Quadrilateral as the superclass of the hierarchy. Make the hierarchy as deep (i.e., as many levels) as possible. Specify the instance variables and methods for each class. The private instance variables of Quadrilateral should be the x-y coordinate pairs for the four end- points of the Quadrilateral. Write a program that instantiates objects of your classes and outputs each object’s area (except Quadrilateral).
