TLDR

To modify Java Look and Feel (L&F), leverage UIManager.setLookAndFeel(). Use it with the class name of the desired L&F. To set it to the system look, here’s the key code:

// Because nothing feels quite like home UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());

For the Java Metal look:

// Built tough like a warrior in shiny armor UIManager.setLookAndFeel(UIManager.getCrossPlatformLookAndFeelClassName());

Use try-catch to handle exceptions. Remember to initialize this before creating any GUI components.

Choosing the right outfit: L&F options

Java provides various ways to dress up your application. This section covers popular Look and Feel options which you can leverage to improve the appearance and optimize your User Interface.

Nimbus L&F: The modern stylist

Nimbus L&F, known for its sleek and modern touch, is an ideal choice for dressing up your application for a modernized look & feel.

// Get ready for your application to strut the runway in Nimbus' modern couture UIManager.setLookAndFeel("javax.swing.plaf.nimbus.NimbusLookAndFeel");

However, remember to verify if your runtime environment favors Nimbus.

Substance L&F: The festive dresser

The Substance project offers an extensive palette of themes to match your festive spirit. Just include the Substance library and make a method call to enter the party.

Exception Handling and User Preferences
