- Answer By True or False , JAVA LANGUAGE A Java interface can contain only constants and abstract methods. A class that implements an interface can define only the methods that are included in the interface. A static variable can be referenced only from a static method. Static variables are also called class variables.What is an abstract class? Choose only one option.(a) An object(b) A class with no methods.(c) A class with no concrete subclasses.(d) A class with at least one undefined message.(e) An interface.Topic: C# Write the C# program with explaining the proper logic used and screenshot of the output which you got in Visual Studio... Difference between static and Instance class in C# Create some classes which implement the concept of method overloading and overriding. Read on difference between Abstract class and Interfaces and find out the example when to use what? Create classes with example of Abstract class and Interface.
- Student Information: student_id, civil_id name, address, phone number, email (Class that contain overloaded method) 1.Draw the Class diagram(UML Diagram). 2.Write a JAVA program for Student Information using method overloading concept (Object Class and Driver Class)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 attributes1. Create abstract class Pet , which is the abstract super class of all animals.1. Declare an integer attribute called legs, which records the number of legs for this animal.2. Define a constructor that initializes the legs attribute.3. Declare an abstract method eat.4. Declare a concrete method walk that prints out something about how the animals walks (include the number of legs).2. Create the Dog class that implements Pet class.1. This class must include a String attribute to store the name and food of the pet2. Define a default constructor that calls the super class constructor to specify that all dogs have 4 legs and name.3. override the eat and walk method.3. Create the Cat class that Implements Pet class.1. This class must include a String attribute to store the name of the pet, and a string to save food .2. Define a constructor that takes one String parameter that specifies the cat's name. This constructor must also call the super class constructor to specify that all cats have…
- 1. Define an interface Measurable. It has a single abstract method: double getArea(); 2. Define an abstract class Shape which has two fields: type and name both of type Strin a. Provide constructor with a single input parameter: name. b. Provide accessor methods for both fields. C. Provide setter method for name. d. Provide toString() method that simply returns the "(type): (name)" e. Shape class implements Measurable interface without implementing its only abs method. 3.Define a java Name class with attributes: String firstname, middle name, lastname. Include the following methods: - A constructor with 3 parameters. Initialize the 3 member variables to the parameters being passed. Also, include the default constructor. - getter and setter methods for all attributes - override toString method Define a class called DebitCard. A debit card has a card number, Name and balance. a) Include a constructor with 3 parameters. Initialize the 3 member variables to the parameters being passed. Also, include the default constructor. b) Include getters/setters for all attributes. c) Add the following member functions: float inquireBalance() float depositCash(float amount) //increases the balance with amount boolean withdrawCash(float amount) // returns true if sufficient amount is available for withdrawal and decreases the balance by amount float interest(float rate) //calculates the interest rate incurred. Assume the parameter rate is considered as…Define a java Name class with attributes: String firstname, middle name, lastname. Include the following methods: - A constructor with 3 parameters.

Write your answers in the space provided. 1. Can you declare a class that contains abstract methods a non-abstract class? 2. Can you declare an abstract class that contains no abstract methods? 3. Can objects be created from abstract class? 4. What is an interface?JAVA PROGRAMMING - Create a class named "Shape" that has rhe abstract methods getArea() and getPerimeter(). - Create a class named "Rectangle", "Square", and "Circle". Override the methods getArea() and getPerimeter() with the right equation in getting the area and perimeter. - For rectangle, create attribute length and width. For square, side. For circle, radius Inputs: 1. Char input for Shape Type (Rectangle, Square, Circle). 2. Dimensions for specific type of Shape Output: Shape: Rectangle Length: 10 Width: 50 Area: 500.00 Perimeter 120.00Create an interface that shall have 2 methods and one string type attribute, also create an implementation class of the interface that shall define both methods (you can print YOUR favorite quote in each method body).
