Write a program that displays the employees Ids together with their first and last names. Use two classes. The first class contains the employee data and separate methods to set and get the ID’s and names. The other class creates objects for the employees and uses the objects to call the methods. Create several employees and display their data
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:

2. Write a program that displays the employees Ids together with their first and last names. Use two classes. The first class contains the employee data and separate methods to set and get the ID’s and names. The other class creates objects for the employees and uses the objects to call the methods. Create several employees and display their data
3. a. Create a class named Circle with fields named radius, area and diameter. Include methods names setRadius(), getRadius(), computeDiameter() which computes a circles’s diameter and computeArea which computes a circle’s area. The diameter of a circle is twice its radius and the area is 3.14 multiplied by the square of the radius.
b. Create a class named TestCircle whose main() declares three Circle objects. Using the setRadius() method, assign one circle a small radius value. Assign another circle a larger radius value and assign the third circle a radius of 1. Call computeDiameter() and computeArea() for each circle and display the results.
