### Java Program: Inheritance and Class Structure

The code snippet illustrates a simple Java program that demonstrates the concepts of classes, inheritance, and method overriding within the context of personal information management.

#### Code Explanation

The program is designed to create two classes: `Person` and `Student`, where the `Student` class extends the `Person` class, showcasing inheritance.

#### Classes and Members

- **Class `Person`:**
- **Attributes:**
- `name`: Stores the name of the person.
- `address`: Stores the address of the person.
- `phoneNumber`: Stores the phone number of the person.
- `emailAddress`: Stores the email address of the person.
- **Constructor:** Takes four parameters to initialize the attributes of the `Person` class.
- **Method:**
- `toString()`: An overridden method that returns a formatted string containing all the personal details.

```java
class Person {
private String name;
private String address;
private String phoneNumber;
private String emailAddress;

public Person(String name, String address, String phoneNumber, String emailAddress) {
this.name = name;
this.address = address;
this.phoneNumber = phoneNumber;
this.emailAddress = emailAddress;
}

@Override
public String toString() {
return "Person: " + name + "\nAddress: " + address + "\nPhone Number: " + phoneNumber + "\nEmail Address: " + emailAddress;
}
}
```

- **Class `Student`:**
- **Attributes:**
- `classStatus`: Represents the academic status or class level of the student.
- **Constructor:** Inherits attributes from the `Person` class and adds `classStatus`.
- **Method:**
- `toString()`: An overridden method that calls `super.toString()` and appends additional student-specific information.

```java
class Student extends Person {
private String classStatus;

public Student(String name, String address, String phoneNumber, String emailAddress, String classStatus) {
super(name, address, phoneNumber, emailAddress);
this.classStatus = classStatus;
}

@Override
public String toString() {
return super.toString() + "\nClass: Student" + "\nClass Status: " + classStatus;
}
}
```

#### Error

**The Person, Student, Employee, Faculty, and Staff Classes**

1) **Design a Class Structure:**
- Create a class named `Person` and its two subclasses named `Student` and `Employee`.
- `Employee` has two subclasses: `Faculty` and `Staff`.
- A `Person` includes attributes such as a name, address, phone number, and email address.
- `Student` includes a class status (e.g., freshman, sophomore, junior, or senior).
- `Employee` includes attributes like salary (double) and date hired.
- Use `java.time.LocalDate` for the date hired attribute.
- `Faculty` has office hours (e.g., “Friday 3-4PM”) and discipline (e.g., “Computer Science” or “Math”).
- `Staff` includes a title attribute.
- Override the `toString` method in each class to display the class name and related data.
- **Task:** Draw the UML diagram using MS Word or PowerPoint for the classes and implement them.

2) **Develop a Test Program:**
- Create a program that generates instances of `Person`, `Student`, `Employee`, `Faculty`, and `Staff`, invoking their `toString()` methods.
- The program should read a text file containing data for these objects, with each line representing one object.
- Determine a format for your data that your program can parse successfully.

3) **Submission Requirements:**
- Submit all Java files.
- Provide the MS Word or PowerPoint file used for drawing UML diagrams.
- Include the data file you created.

4) **Hints:**
- Example of creating a `LocalDate` object:
```java
LocalDate date = LocalDate.of(2020, 1, 8); // year, month, date
```

This exercise helps in understanding class hierarchies, inheritance, and practicing programming concepts in Java, including object creation and method overriding.
