Calculator keypads, custom grids, or uniformly sized panels. JTextArea textArea = new JTextArea(5, 20); // 5

Applications require a heavy root window to interact with the OS window manager. The most common top-level container is JFrame . Other examples include JDialog and JApplet (deprecated).

To start building Swing applications, follow these steps:

setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE) : By default, closing a window merely hides it while the background Java process continues running. This line ensures the JVM completely shuts down when the user clicks 'X'.
