What is Java Swing?

Java Swing is a part of Java's standard library used for building graphical user interfaces (GUIs) for desktop applications. It provides a set of 'widgets' like buttons, text fields, tables, and more, which developers can use to create interactive windows and forms. Swing is platform-independent and written entirely in Java, offering a rich set of features for customizing the look and feel of applications. It's widely used for enterprise, educational, and hobbyist software projects.
