Step by step
Solved in 3 steps
- You have a method that requires an argument that is an instance of the superclass, and it expects you to provide it. It will function properly if you provide it with an object of a subclass rather than a superclass. Is it even possible? Where is the value in that?Write a java code that: a) Creates an abstract method in a superclass, then overrides it in a subclass. (Only show the methods in both classes). b) Provides a method PrintInfo () that prints your group info and can be used only in classes of the same package. c) Provides a non-overridden area() that calculates area. (choose a shape)Write a java program Write a class named Employee with name and salary as private data fields. Add a constructor with both parameters. Write a class named Manager which unherits the Employee class. Add an instance variable, named department, of type String and 15 private. Add a constructor in the subclass class and a toString () method that prints the manager's name, department, and salary [Hint: Add a tastanel) method in the super class as well]. Create objects of Manager and Employee dass
- In your code, you have a method that takes a superclass instance as a mandatory argument. An instance of a subclass, rather than a superclass object, will suffice. Can we do that, if so? Where is the value in that?Write in java code: a) Write class Vehicle that is superclass and abstract write only one line in the class declaration(first line):b) Class Vehicle is a superclass that contains three non-abstract methods (three methods that are concrete, implemented in the class Vehicle); then class Vehicle cannot be abstract; T/F?c) The first step in problem-solving process is the Requirement Analysis ; T/F?d) Write the method salary1() that is abstract with two parameters (integer and double):e) The final method is a method in the super class that cannot be overridden in its subclasses; T/F?You have a method which requires an argument of type superclass. It will function if you supply a subclass object rather than a superclass object. Is it permissible? What is the purpose?
- Type a Java method constructor for the "book" Class, which takes values as parameters for all of these attributes.The" book " Class has the following properties: title (string), author (string), year (int), pages (int).Java program Make a class Employee with a name and salary. Make a class Manager inherit from Employee. Add an instance variable, named department, of type String. Supply a method toString that prints the manager’s name, department, and salary. Make a class Executive inherit from Manager. Supply appropriate toString methods for all classes. Supply a test program that tests these classes and methods.You have a method that expects an object from the superclass to be supplied as a parameter. If you offer it a subclass rather than a superclass object, it will work. Is it permitted? What's the point?
- Overriding a method such as toString(), equals() methods etc in a user defined classIf myObject is an object in Java, we get its ____ from its member variables and its _____ from its methods.What is method overriding in Java? Creating a new method with the same name and parameters as a method in a superclass None Removing a method from a subclass that was inherited from a superclass Creating a new method with a different name and parameters as a method in a superclass
