Solved in 3 steps
- Method binding may be either dynamic or static (i.e., between virtual and nonvirtual methods).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.Polymorphism in Java In the class “Phone”, there is a method call() which in default prints “Calling Emergency services…”. Override this method by accepting a string called number. Accept for a number as input. If input is 0, call the default method. Inputs 1. A string 1234567 Sample Output Enter number: 1234567 Calling number 1234567...
- Crete a program that implements at least 4 combination of method overriding and overloading. Decide which class to use to properly illustrate your solution.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).Classes – Write a class to represent a AlternativeEnergyCar. Select the fields and methods that fit the modeling of an alternative energy car. Make sure to include code for the constructors, set/get methods, a toString() method.
- Two methods are not defined in the AbstractCollection class but must be defined in its subclasses for its other methods to function properly. Which methods are these? *PythonWrite 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)Suppose a parent class has a few methods that the child would like to use, but the methods are not appropriate for the child. What can the child do to make the methods 'usable' for itself?
- The Factory method design pattern is advantageous since it enables dynamically creating new objects of a certain kind. True UntrueAll of the abstract methods that the parent class has defined must be implemented by any subclass. What do you think?Explore advanced scenarios of method overriding, such as overriding static methods and constructors, and their implications.
