Create an employee class based on this UML class diagram. The setters should prompt the user for the information to set the value of the instance variables. These are the validation rules:

$-$The ID has to be $4$ characters long. If it is invalid the characters XXXX have to replace the invalid ID$.$

The minimum length for a first or last name is $2$ characters and the maximum length is $20$ characters. If invalid the first or last name have to be replaced with XXXX$.$

The pay rate has to be between $0$ and $1000000.$ If invalid the pay rate has to be replaced with $0.$

Use the ValidString Function to validate the first name, last name and empID. The invalid message should include which item was incorrect. For example if the first name was incorrect it should display "Invalid first name. Set to XXXX$"$

Use the ValidatePayRate Function to validate the pay rate and display an invalid message that states the following for an invalid pay rate: $$Invalid pay rate. Enter a value between $0$ and $1000000".$

The DisplayEmployee getter function should display all of the employee information.

Create a program that uses the Employee class to create an array of employee objects based on the user's input. It should then display all of the employee data in the array.

Example:

Module

main$()$

Declare Integer employeeNo

Display "How many employees do

you want to enter?" Input employeeNo
