Question
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. SSN needs to be entered as a 9-digit string without separators. You need to create these two classes:
- SSNStructureException for when any character in the social security number is not a digit.
- SSNLengthException for when the social security number entered, without connection characters (dash, or space), has a length other than nine.
- Download the template file, EmployeeException.txt, and save it as EmployeeException.java
-
public class EmployeeException{
-
//*** Task #1: define the instance variables//
-
*** Task #2: define constructor with no arguments//
-
*** Task #3: define constructor passing values for all arguments//
-
*** Tasks #4: define accessor, mutator, and write out methods for name attribute//
-
*** Tasks #5: define accessor, mutator, and write out methods for sSN attribute// Display the SSN as ddd-dd-dddd//***
-
Tasks #6: define accessor, mutator, and write out methods for salary attribute
//*** Tasks #7: Define method writeOutput() that display all information about the employee.//
-
*** Tasks #8: Define equals method, having argument of type EmployeeException}
-
- Go through the template file and identify the tasks you have to complete, which are clearly marked throughout the file. Complete all the required tasks.
- Download the template file, EmployeeExceptionDriver.txt, and save it as EmployeeExceptionDriver.java.
-
import java.util.Scanner;
-
public class EmployeeExceptionDriver{
-
public static void main(String [] args){
-
//*** Task #1: define the variables required for the program
-
//*** Task #2: define and instantiate variable of type Scanner to be able to read from
-
//*** Task #3: create a loop in which you enter the data for employee.
-
//*** Task #4: inside the loop, instantiate each element of the array with the constructor
-
//*** Task #5: read the name of the employee
-
//*** Task #6: read the salary of the employee
-
//*** Task #7: read SSN using the exceptions blocks
-
//*** Task #8: ask the user if there are more employees to enter
-
//*** Task #9: calculate the average salary
-
//*** Task #10: display the information about all employees with a note if their salary// is above average, under average or average.
-
System.out.println("No more employees.");

![### Eclipse IDE for Java Development
#### Programming Example: Managing Employee Data
In this example, we demonstrate how to manage employee data using Java code within the Eclipse IDE. Below is a detailed transcription and explanation of the code provided:
#### Code Snippet
```java
// Task #5: read the name
System.out.print("Enter employee #1's name: ");
nameOfEmployee = keyboard.nextLine();
e[i].setName(nameOfEmployee);
System.out.println();
// Task #6: read the salary
System.out.print("Enter loyee #1's salary: ");
salaryOfEmployee = keyboard.nextDouble();
e[i].setSalary(salaryOfEmployee);
System.out.println();
keyboard.nextLine();
// Task #7: read SSN using try-catch
try {
System.out.print("Enter employee #1's SSN (9 digits): ");
ssnOfEmployee = keyboard.nextLine();
if (ssnOfEmployee.length() != 9) {
throw new SSNLengthException(ssnOfEmployee, ssnOfEmployee.length());
} else {
for (int j = 0; j < 9; j++) {
// Additional processing if necessary
}
}
} catch (SSNLengthException e) {
System.out.println("Invalid SSN length for employee #1.");
}
```
#### Console Output
```
Enter employee #1's name: John
Enter loyee #1's salary: 2200
Enter employee #1's SSN (9 digits): 123456789
Continue entering employees? (Y for Yes, or N for No) y
Enter employee #2's name:
Enter loyee #2's salary:
```
#### Explanation of the Code and Output
- **Task #5:** The program prompts the user to input the name of Employee #1 using `System.out.print("Enter employee #1's name: ");`. The `keyboard.nextLine()` function captures the input and assigns it to `nameOfEmployee`. The name is then set for the employee object using `e[i].setName(nameOfEmployee)`.
- **Task #6:** The program asks for the salary of Employee #1. It uses `keyboard.nextDouble()` to read the salary and sets it using `e[i].setSalary(salaryOfEmployee)`. Note the typo in the prompt ("Enter loyee" instead of "Enter employee").
- **Task #7:**](https://content.bartleby.com/qna-images/question/5919289c-3531-49df-94d9-1097b7b08cec/5a143102-128e-4c7c-bf17-d32a69a4ba1d/6xn6968_processed.png)
