Create a base class with an abstract print( ) method that is overridden in a derived class. The overridden version of the method prints the value of an int variable defined in the derived class. At the point of definition of this variable, give it a nonzero value. In the base-class constructor, call this method. In main( ), create an object of the derived type, and then call its print( ) method. Explain the results. (JAVA)
1). Write a java abstract class called Solid and you will derive two classes – Cylinder and Sphere – from Solid. The class Solid Member variables type whose data type is String. For example, the type could be sphere, cube, parallelepiped. 2). The methods should include: A default or null constructor A constructor that initializes the value of type Getters and Setters An abstract method to find volume whose signature is public abstract double findVolume(); An abstract method to find surface area whose signature is public abstract double findSurfaceArea() a toString method that returns a string like the following Solid Type: Sphere an equals method that returns true if two Solid objects have the same type and false otherwise. 3). The class Cylinder - Cylinder will extend Solid Member variables: Cylinder inherits type from Solid radius of type double height of type double Methods: a default or null constructor a constructor that initializes type, radius, and height. type will always…

1- Create a class SchoolKid that is the base class for children ar aschool . It should have attributes of the child’s name and age ,the name of the child’s teacher ,and the greeting. It should haveappropriate accessor and mutator methods for each of the attributes. Derive a class ExaggeratingKid from schoolkid , as described above . The new class should override the accessor method for the age , reporting the actual plus 2. It also should override the accessor for the greeting ,returning the child’s greeting concatenated with the words “I am the best”.

Answer the given question with a proper explanation and step-by-step solution. The base class Pet has protected fields petName, and petAge. The derived class Cat extends the Pet class and includes a private field for catBreed. Complete main() to: create a generic pet and print information using printInfo(). create a Cat pet, use printInfo() to print information, and add a statement to print the cat's breed using the getBreed() method.
An employee has a name, phone number and salary. A coach is a person with a senitority status, one of: junior, lead, and senior. Define the possible status values as constants. A staff is a person with a job title and job descrption. Your programming task is to Implement as abstract class named Employee and two subclass name Coach and Staff in Java as defined above Provide constructors for classes to initalize private variable Override the toString() method in each of the classes in task 1 to display the class name and the person's name Write an application to create objects of type Coach and Staff and print the person's name and the class name of the objects
Create a class Animal and Add a protected data member named id of integer type. Add get/set methods for id data member in Animal class with public access. Also provide default constructor this should initialize id to 0. Also provide parameterized constructor and toString method. Add an abstract method tellAboutSelf method to Animal class with public access Add another abstract method speak method to Animal class. Reptile, Bird, Mammal Next create the three child classes which extends form Animal class. Add a default constructor to each of the above created class. The constructor should initialize the id data member id, Reptile, Bird and Mammal, to 1, 2 and 3 respectively also it display a message “(class Name)’s default constructor”. E.g. for Bird it says “Bird’s default constructor”. Add a parameterized constructor to each of the above created class. The constructor should initialize the id data member, Reptile, Bird and Mammal, to the specified id passed to the constructor also it…
Create an abstract class called Employee that has an abstract method called calculatePay() which calculates the total pay per employee using the rate per hour = R100. The method should accept the number of hours the employee has worked. Create a child class called employeeChild and provide the implementation. In the main method invoke that method and get the number of hours worked from the user and pass it to the called method.
