Student Management System

Project Overview

The Student Management System is a simple Java-based application designed to manage student and teacher information. This system allows users to add, delete, and update student records, as well as display all student information. It utilizes Object-Oriented Programming (OOP) concepts such as inheritance, classes, and methods to organize the functionality. The project includes the following core classes:

• Person: A base class representing common attributes (name and age) for all people.
• Student: A subclass of Person representing a student with additional attributes such as id and grade.
• Teacher: A subclass of Person representing a teacher with additional attributes such as section and salary.
• StudentManagement: A class that manages an array of students, including methods for adding, deleting, and updating student records.

Features

Person Class

• Represents a generic person with basic attributes: name and age.
• Includes getters and setters for these attributes.

Student Class

• Inherits from Person and adds additional attributes: id and grade.
• Methods to get and set id and grade.
• Additional methods such as addStudent, deleteStudent, and displayStudent can be added to manage students effectively.

Teacher Class

• Inherits from Person and adds additional attributes: section and salary.
• Methods to get and set section and salary.
• Additional methods such as addTeacher, deleteTeacher, and displayTeacher can be added to manage teachers effectively.

StudentManagement Class

• Manages an array of students with the following functionality:
  • Add a Student: Adds a new student to the system with name, age, ID, and grade.
  • Delete a Student: Deletes a student by their ID and shifts the remaining students accordingly.
  • Change Student Information: Allows modification of a student's information, either fully or partially.
  • Display Students: Displays the information of all students currently in the system.
  • Method Overloading: Includes an overloaded changeStudentInfo method that allows changing only the student's name.

Requirements

• Java 8 or higher

Example Usage

StudentManagement studentSystem = new StudentManagement(10);

// Add students
studentSystem.addStudent("John Doe", 20, 101, 85.5);
studentSystem.addStudent("Jane Smith", 22, 102, 90.2);

// Display all students
studentSystem.displayStudents();

// Change student info
studentSystem.changeStudentInfo(101, "John Doe Updated", 21, 88.5);

// Delete a student
studentSystem.deleteStudent(102);

// Display all students again
studentSystem.displayStudents();
