OOPs

In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career.

Constructor

The easiest way to think of a constructor in object-oriented programming (OOP) languages is:

Write a java program to create a class named shape. In this class we have three sub classes sphere, cylinder and con .Each class has two member functions named shapename () that returns the name of the shape and volume() that we will return the volume of this shape.

Please someone help me how can i use java to create an abstract class called Worker and 2 subclasses HourlyWorker with monthlybasic salary and allowance and SalariedWorker pay rate and hour worked. Every worker has a name (use the Name class provided) and the year joined. Declare the data fields in the abstract class as protected. For each class, You only need to provide a parameterized constructor and implement the toString method. You may omit the set and get methods for each class.Both the HourlyWorker and SalariedWorker classes are required to provide anoperation to calculate the worker’s monthly salary.-The salaried worker is paid a monthly basic salary + allowance.-An hourly worker is paid payRate * hoursWorked
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)
