This document defines an AcademicPerformance class that creates a GUI application for forecasting students' academic performance. It imports various Java libraries for GUI components and event handling. The class initializes labels, combo boxes, buttons, and text areas to display student grades and forecast results. It defines handlers for button click events to clear inputs, forecast results, and display additional information. The main method sets up the frame, content panel, menu bar, and adds all components before making the frame visible.
