Develop a java application named "Student Information Management System", where the Student Information Management System is a Java-based application designed to handle student records efficiently through a graphical user interface (GUI). This system allows users to add, load, and save student data, including details such as the student's name, ID, and GPA. The program is structured into two main components: the Student class, which defines the data model for student records, and the gui class, which provides an interactive interface for managing these records. The primary goal of this system is to simplify the process of storing and retrieving student information while ensuring data integrity through basic validation checks. The GUI makes the application user-friendly, eliminating the need for manual file editing or command-line operations.
