Student Record Management System (Java CLI)

Objective

This project is a CLI-based CRUD system for managing student records.
It demonstrates how to use classes, ArrayList, loops, and methods in Java to build a menu-driven application.

---

Tools Used

• Java (JDK)
• VS Code
• Terminal

---

Files

• StudentRecordManagement.java → Main program file
• Student class → Represents a student entity with fields (ID, Name, Marks)

---

Features Implemented

1. Add Student

   • Takes input from the user (ID, Name, Marks) using Scanner.
   • Stores the student as an object in an ArrayList.

2. View Students

   • Prints all student records.
   • Used Enhanced For Loop for simplicity.
   • toString() method is overridden in Student class to display student details cleanly.

3. Update Student

   • Searches for a student by ID.
   • If found, updates name and marks.
   • Used Enhanced For Loop for iteration.

4. Delete Student

   • Searches student by ID and deletes the record from ArrayList using remove() method.
   • students.remove(s) is used because it directly removes the matching object.

5. Exit Option

   • Gracefully terminates the program.

---

Why These Concepts Are Used?

• Class Student → To represent real-world entities (ID, name, marks) as objects.
• ArrayList → Dynamic data structure to store multiple student objects, supports add/remove easily.
• Enhanced For Loop → Cleaner and shorter than traditional for loop when traversing the list.
• toString() Method Override → Allows direct printing of student details without extra formatting code.
• remove() Method → Deletes a specific student object from the list.
• Scanner → For console input (CLI-based interaction).
• While Loop with Menu → Provides continuous interaction until user chooses exit.

How to Run

1. Open terminal in project folder.
2. Compile the program:

   javac StudentRecordManagement.java
