Java Swing Menu Implementation and Shape Manipulation

This guide explores how to create a simple Java Swing application with a dynamic JMenuBar for altering shapes. Key features include adding JMenuItems for actions like resizing and changing color, driven by ActionListener. Users can utilize keyboard shortcuts for quick commands, ensuring an interactive experience. The menu provides functionalities to manage shapes such as circles and diamonds, with visual updates reflecting user inputs. The application leverages the Java API for graphics and user interface components effectively.
