Question

Design two sub- classes of Employee...SalariedEmployee and HourlyEmployee. A salaried employee has an annual salary attribute. An hourly employee has an hourly pay rate attribute, an hours worked attribute, and an earnings attribute. An hourly employee that works more than 40 hours gets paid at 1.5 times their hourly pay rate. You will decide how to implement constructors, getters, setters, and any other methods that might be necessary. 1. 2. (20 points) Draw a UML diagram for the classes. (80 points) Implement the classes, and write a test program that creates a salaried employee and two hourly employees. One of the hourly employees should have hours worked set to less than 40 and one should have hours worked set to more than 40. The test program should display all attributes for the three employees. To keep things simple, the employee classes don’t need to do any editing.

Here is my code so far:

import java.util.Scanner;

public class Assignment6_lgolden81 {

public static void main(String[] args) {

//Declaring the variables for the main method

String fname, lname, city, state, street;

int employeeNO, zip;

int month, day, year, size;

//This Scanner class object is used to get the input entered by the user

Scanner input = new Scanner(System.in);

System.out.println("Please Enter the Desired Number of Employees: ");

size = input.nextInt();

//This is the Array used to hold the employee class information

Employee emp[] = new Employee[size];

//This loop is used to get the employee information

for (int i = 0; i < size; i++) {

//This portion of the program gets the input entered by the user

//prints out the employee number

System.out.println("\nEmployee #" + (i + 1) + ":\n");

input.nextLine();

//Prints out the employee's first name

System.out.println("\nEnter the Employee's First Name:");

fname = input.nextLine();

if (fname.length() < 1) {

System.out.println("Invalid Input: Please Enter a Valid First Name!");

System.exit(0);

}

//Prints out the employee's last name

System.out.println("\nEnter the Employee's Last Name:");

lname = input.nextLine();

if (lname.length() < 1) {

System.out.println("Invalid Input: Please Enter a Valid Last Name!");

System.exit(0);

}

///Prints out the employee's ID number

System.out.println("\nEnter the Employee's ID Number:");

employeeNO = input.nextInt();

input.nextLine();

if (employeeNO < 1) {

System.out.println("Invalid Input: Please Enter a Valid Employee ID Number!");

System.exit(0);

}

//Prints out the employee's street address

System.out.println("\nEnter the Street Address:");

street = input.nextLine();

if (street.length() < 1) {

System.out.println("Invalid Input: Please Enter a Valid Street Name!");

System.exit(0);

}

//Prints out the name of the City

System.out.println("\nEnter the City:");

city = input.nextLine();

if (city.length() < 1) {

System.out.println("Invalid Input: Please Enter a Valid City Name!");

System.exit(0);

}

//Prints out the name of the State

System.out.println("\nEnter the State (ex. GA):");

state = input.nextLine();

if (state.length() < 1) {

System.out.println("Invalid Input: Please Enter a Valid State Name!");

System.exit(0);

}

//Prints out the employee's zip code

System.out.println("\nEnter the Zip Code:");

zip = input.nextInt();

if (zip == 0) {

System.out.println("Invalid Input: Please Enter a Valid Zip Code!");

System.exit(0);

}

//While loop used to get the employee's hire date (Month) and makes sure the input is valid

while (true) {

continue;

Answer 1

Representative Class subtleties are not given in the inquiry depiction. Henceforth, the subtleties are accepted for advantageous understanding and utilized in the UML Diagram. Kindly don't hesitate to change according to the planned needs.

UML Diagram:

Employee Class:

1. Employee is the parent class as perceived from the inquiry.
2. The factors and strategies are accepted as subtleties were not given being referred to.

HourlyEmployee is the sub class.:

1. Hourly_Payrate is the variable to store hourly payrate.
2. Hours_Worked is the variable to store number of hours worked.
3. Profit is the variable to store the gross income.
4. SetHours() is the setter strategy to set Hourly_Payrate and Hours_Worked.
5. GetEarnings() is the getter technique to get gross profit. This technique computes the profit dependent on the quantity of hours worked. In the event that >40 hours, at that point 1.5 occasions the hourly payrate.

SalariedEmployee Class:

1. AnnualSalary is the variable to store the compensation of the representative.
2. Income is the variable to store the gross profit.
3. SetAnnualSalary() is the setter technique to set yearly compensation for the worker.
4. GetEarnings() is the getter technique to get gross income.
