Write a Java program that defines a Shape class having an abstract method draw(). Inherit Rectangle, Triangle, and Square classes from Shape and provide definition of the abstract method. Write a Driver class that receives type of the shape as input from the user and creates an object of the required class through polymorphism. Then the draw() method of required shape is invoked that further receives inputs from the user depending upon the type of the shape. For example to draw a square just one side length is required, for rectangle two sides are required and for triangle only one length of 90 degree side is required. Then for each draw() implementation, filled shape of asterisks (*) should be drawn on console.   Give the screen shots of output...and the program title is named as "Mubeen Aslam 18-ARID-2666"

Design a Java interface called Priority that includes two methods: setPriority and getPriority. This interface would define a way to establish numeric priority among a set of objects. Your numeric priority values should be on a scale. For easy comparing of priorities, make 1 the lowest priority. It should be more complex than just 1, 2, 3 (low, medium, high). Define constants in the interface for the low, medium, and high priority values. Design and implement a class called Task that represents a task (e.g., something on a to-do list) that implements the Priority interface from above, as well as the Comparable interface from the Java standard class library. A task should have some sort of description. Illustrate your design with a UML class diagram. Create a driver whose main method exercises some Task objects. Make sure you have enough tasks to produce comparisons where a given task is higher, lower, or equal in priority to some other task. Implement the interface such that the tasks…

USING JAVA Write these: An interface called Shape that has two methods: area and perimeter. A class Rectangle that implements Shape and has a length and a width. A class Circle that implements Shape and has a radius. For each class, write the needed constructors, getters, setters, and a toString method that stringifies the instance variables in a readable format. Supply a test program that instantiates an instance of each class and exercises each method defined for the class.

In Java!!!!!This is a multi-part question. Consider the following UML diagram on attached image: 1.Write Java classes corresponding to the UML diagram. 2. Write getters and setters for all classes 3. Write non-default constructors for each class that initializes all instance variables to values passed as arguments to the constructor 4. Write toString method for each class 5. Modify Vehicle class to maintain inventory (list of all vehicles created) and print the list. What variable(s) you need to add? What additional method(s) you need? What else needs to be modified in the Vehicle class? Do you need to modify any of the descendant classes and explain your answer (if not: why not; if yes, describe what changes).
