Please follow the steps to complete JAVA PROGRAM
Create a class, EmployeeException, that has the following attributes:
name: String
SSN: String
Salary: double
The methods required in this class are:
A constructor with no arguments that sets the attributes at default values
A constructor that passes values for all attributes
Accessor, mutator, display method for each attribute. An example of a display method for an attribute is writeOutName(): void, in which you just display the name:System.out.println("Employee Name: " + name);
An equals method that has an object of type Employee as argument, and returns true if two employees have the same name, salary, and SSN.
Write a driver program for the Employee class that uses an array that can hold up to 100 employees (the array will be of EmployeeException type). However, the user should be free to enter as many employees as needed.
The driver class should use two exception classes to signal the user that the SSN entered is not correct.…
JAVA PROGRAMMING - 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.
CS Java Program (NEED HELP WITH THE ACTUAL CODING PART):
For this project, you will create an application for a zoo.
You will need to create a class that implements the iAnimal interface (provided below), and use one other class for an additional animal that implements the iAnimal interface as well (provided below). Modify the animal classes that you will use for this project so they implement Java’s comparable or comparator interface.
You will also need a Main Class that will provide a user interface for this application. This can be a console-based interface. Tasks can be performed in one or more methods as needed.
The Main Class should have one or more methods that handle these tasks:
Create a new instance (object) of each of the animal classes and pass the user input as arguments to the object's mutator methods to set the private instance data for the appropriate animal class.
Create an ArrayList of type iAnimal and add the new instance created in task 1 to the ArrayList. Before…

- Laboratory Exercises – Java Lesson 5: Creating Classes and Objects 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.

A default constructor which sets the metroID to a random number between 1 and 1000, the station number to 0, the direction (int), and the passTotal to 0 (train is empty). A constructor with one parameter; the parameter is the metro id.

Add a separate main class with the main() method to test all public methods in both ValidatorNumeric and ValidatorString classes. The main() method should create the necessary objects and run the user interaction as shown above. The ValidatorNumeric class is responsible for capturing user prompt and a range of valid numeric inputs. Its methods display the prompt and accept input from the user. It should provide the following public interface: // Default constructor ValidatorNumeric() // Specific constructor taking params as follows: ValidatorNumeric( String prompt, int min, int max ) // Another specific constructor taking params as follows: ValidatorNumeric( String prompt, double min, double max ) // Method that shows user prompt and gets an int from the user: public…arrow_forward
