Millised on erinevused klasside kasutamises erinevates Java versioonides?

In different versions of Java, new features and improvements in working with classes have appeared:

• Java 5: generics were introduced, allowing the creation of type-safe classes and collections.
• Java 7: support for try-with-resources was added for automatic resource closing, affecting the use of classes implementing AutoCloseable.
• Java 8: lambda expressions and functional interfaces appeared, changing the approach to implementing classes and interfaces.
• Java 9 and later versions: the modular system (JPMS) was introduced, affecting class visibility between modules.

Additionally, each version improves performance and adds new APIs, expanding the capabilities of classes. However, the basic syntax for declaring classes remains backward compatible.
