JPanel

A JPanel is a container in Java's graphical user interface (GUI) framework that holds and organizes other GUI components like buttons, text fields, or images. Think of it as a customizable panel or section within a window where you can arrange and display various elements, making the interface structured and easier to manage. Developers use JPanels to group related components together and control their layout, ensuring a clean and functional user experience. It effectively helps in designing visually organized and interactive applications.
