Java Swing is a part of the Java Foundation Classes (JFC) for building window-based applications. It provides a wide range of GUI components like buttons, text fields, and tables, offering platform independence and customization. Key features include lightweight components, extensibility, and a rich set of widgets. The core components are organized in a hierarchy, with classes like `JComponent`, `JButton`, `JTextField`, and `JMenu`. Swing allows developers to create interactive and professional desktop applications. A simple example demonstrates a window with a button and text field that displays a message when clicked.

Apple removed the Touch Bar from its 2021/22 MacBook Pro models due to mixed user feedback. Introduced in 2016, the Touch Bar was a slim OLED display that replaced function keys, providing app-specific controls. However, users found it largely unnecessary, preferred physical keys, and reported technical issues like bugs. The Touch Bar also required a learning curve, which wasn’t embraced by all. Some speculate that the removal could be a strategic move, with Apple potentially planning to reintroduce an improved version in the future, similar to innovations seen in Asus's ZenBook series. Ultimately, Apple's decision may reflect a balance between innovation and user satisfaction.
