- Please do it in JavaScript or C# 1) Design and implement the class structure for a drawing application. A drawing is made up of a canvas that contains a collection of three different shapes: circles, lines, and boxes. Each shape can be drawn by calling a Draw() method for that shape. The canvas class should also have a draw method that draws all of the shapes it contains. You don’t have to actually draw anything on a screen; you can simulate drawing by writing a message to the console.For example, the code snippet: canvas.Draw();Drawing a circle at...Drawing a line at...etc. (For each shape on the canvas) 2)(Bonus) Consider re-writing the above answer (#1) differently where the canvas does not contain the shapes, but is able to draw any of the three shapes passed to it. Re-design canvas.Draw() if you need to. Your main() program should ask for user input on what shape to draw. Ask once, draw, then exit.could produce something like the following output to the console:Q2: Write the Java code corresponding to the following UML diagram.

- JAVA Practice Question for Midterm Write a class with a constructor that accepts a String object as its argument. The class should have a method that returns the number of vowels in the string, and another method that returns the number of consonants in the string. Demonstrate the class in a program by invoking the methods that return the number of vowels and consonants. Print the counts returned. Imagine you are developing a software package for an online shopping site that requires users to enter their own passwords. Your software requires that users’ passwords meet the following criteria: The password should be at least six characters long. The password should contain at least one uppercase and at least one lowercase letter. The password should have at least one digit. a program that asks the user to enter a password, then displays a message indicating whether it is valid or not.Java- Suppose that Vehicle is a class and Car is a new class that extends Vehicle. Write a description of which kind of assignments are permitted between Car and Vehicle variables.Java - Access Specifiers Create a class named Circle that has attributes radius, area, and circumference and make the attributes private. Make a public method that sets the radius and a method that prints all attributes. Ask the user input for radius. Note: Use the PI from the math functions Inputs A line containing an integer 10 Sample Output Radius: 20 Area: 1256.64 Circumference: 125.66
- Instructor note: This lab is part of the assignment for this chapter. This lab uses two Java files, LabProgram.java and SimpleCar.java. The SimpleCar class has been developed and provided to you already. You don't need to change anything in that class. Your job is to use the SimpleCar class to complete the specified tasks in the main() method of LabProgram.java Given two integers that represent the miles to drive forward and the miles to drive in reverse as user inputs, create a SimpleCar object that performs the following operations: Drives input number of miles forward Drives input number of miles in reverse Honks the horn Reports car status The SimpleCar class is found in the file SimpleCar.java. Ex: If the input is: 100 4 the output is: beep beep Car has driven: 96 miles1.Create a java application called Employee, then create 2 classes according to the following UML diagram.

You will need to create a class that implements the iAnimal interface (provided below), and use one other class for an additional animal that implements the iAnimal interface as well (provided below). Modify the animal classes that you will use for this project so they implement Java’s comparable or comparator interface. You will also need a Main Class that will provide a user interface for this application. This can be a console-based interface. Tasks can be performed in one or more methods as needed. The Main Class should have one or more methods that handle these tasks: Create a new instance (object) of each of the animal classes and pass the user input as arguments to the object's mutator methods to set the private instance data for the appropriate animal class. Create an ArrayList of type iAnimal and add the new instance created in task 1 to the ArrayList. Before…

An object of this class will have the attributes: Minimum accepted value Maximum accepted value • Prompt String and the following method: getValue() displays the prompt and reads a value from the user. If the value read is not within the allowed range, the method should display an error message and ask the user for a new value, repeating these actions until an acceptable value is entered. The method then returns the value read.Write the code below for the Computer class. The Computer class must be an abstract class, and have the following methods and attributes: • a public string called HostName • a private int called MemorySize • a public abstract method called shutdown that takes no arguments and returns nothing • a public abstract method called runProgram that takes a String for the name of the program and returns a boolean. • Also include getter/setter methods for the attributes
