🎓 Student Grade Tracker

A Java console-based application designed to efficiently manage student records and academic performance. The application allows users to add, view, search, update, delete, and sort student records while automatically calculating grades and generating detailed summary reports.

This project was developed as part of my Java Programming Internship at CodeAlpha and demonstrates the practical implementation of Core Java concepts, Object-Oriented Programming (OOP), Collections, Exception Handling, and Input Validation.

🔍 Search Functionality

The application provides two ways to search for students:

Search by Student ID

Each student is identified using a unique Student ID.

Enter Student ID: 1001

Search by Student Name

The name search supports partial and case-insensitive searching.

For example, if the student's name is:

Raj Pandey

The student can be found using:

Raj
raj
Pandey
PANDEY
Raj Pan

This makes searching student records easier and more flexible.
