Static nested and inner classes in Java are used when classes have a logical relationship with or are intimately associated with the outer class within which they are defined. Local classes are classes defined within a scope and can only be accessed and used within that scope. They're the perfect tools to use when you want to limit the visibility of your classes. Through this course, learn to create and use static nested classes defined within an outer class. Explore how a closer relationship with an outer class can be expressed using inner classes and why access modifiers do not apply to local classes. And define and use local classes created with a code block. When you're finished with this course, you'll be able to pick the right kind of class for your use case and correctly implement nested classes, inner classes, and local classes.

    In this video, you'll learn how to illustrate how static nested classes work in Java. You'll discover that a static nested class is a nested class defined within an outer class. Typically, you define your classes in their own files when you set up your Java project. However, a nested class is defined within an outer class and thus the nested class is logically associated with the outer class. FREE ACCESS
