[[Class (computer scienceprogramming)|Classes]] are fundamentals of an object-oriented language such as Java. They contain members that store and manipulate data. Classes are divided into ''top-level'' and ''nested''. Nested classes are classes placed inside another class that may access the private members of the enclosing class. Nested classes include ''member classes'' (which may be defined with the ''static'' modifier for simple nesting or without it for inner classes), ''local classes'' and ''anonymous classes''.
