Unnamed Classes and Instance Main Methods in Java 21

Date: 2024-03-22

Java 21 introduces unnamed classes for concise, single-use implementations, eliminating the need for explicit class names. It also allows instance main methods, enabling object-oriented programming from the application's entry point by directly accessing instance variables and methods. These features improve code readability, reduce boilerplate, and promote a more object-centric design. Unnamed classes are ideal for small, temporary implementations like event listeners, while instance main methods facilitate a smoother transition to object-oriented principles in larger applications.
