Create a class named Employee with a method information. Then take the input of n number of Employees name, Job Id, Salary, phone number, address, Designation from user input. Throw InvalidSalaryException if salary is negative and InvalidNameException if name length is less than 3. Otherwise Store all information in a text file named EmployeeInformation.txt. Now create another class named EmployeeData with a method Data which will Read Employee Information from the Employeelnformation text file, Store name job Id,Salary in an ArrayList and phone,address,designation in an array. Then pass it to the hSalary method as a parameter. Create another abstract method ISalary in this class. Now create a class named HighestSalary with a method hSalary which will calculate the second highest paid employee information using employee Data(received in parameter). Write the information (name, Job id, salary, phone number, address, designation) of that person in another text file named highest.txt. Now create another Class LowestSalary which will inherit EmplyoeeData Class.Now calculate lowest paid employee information . Write the information (name, Job id, salary, phone number, address, designation) of that person in another text file named lowest.txt. Create an interface named Salary with methods allData, lowest,highest,average. Create another Class Named Display which will implement Salary interface. Read lowest and highest salary from the highest and lowest text file and calculate average of both salaries. Print lowest with person details ,highest with person details, average and all employee information. Note: lowest method will read lowest,txt ,highest will read highest.txt and allData will read employeeInformation txt Now create a class Main with a main method which will use to create objects and call methods.
