Java Programming for Complete Beginners - Java 16 - Java Tip 07 - Final Classes and Final Methods

The video tutorial explains non-access modifiers in Java, focusing on the 'final' modifier for classes and methods. It discusses how declaring a class as final prevents it from being extended, using examples like the String and Integer classes. Similarly, a final method cannot be overridden, ensuring the method's behavior remains unchanged in subclasses. The tutorial highlights the importance of using final modifiers to maintain class integrity and prevent unwanted modifications.
