A class in Java is a template that is used to create and define objects, object data types, and methods. Classes as a whole are categories and objects are items within each category. A class declaration constitutes of the following parts: Modifiers. Class name.
In computer science, a type class is a type system construct that supports ad hoc polymorphism. This is achieved by adding constraints to type variables in parametrically polymorphic types.
There are five kinds of classes: package-level , nested top-level , member , local , or anonymous . (The last four kinds are called inner classes . * A throw-away class that illustrates the five kinds of Java classes.
There are several uses for a Class object. For example, say I want to create an instance of a class based on some class name stored in a config file.
String className = config.myClass;
Class clazz = Class.forName(className);
Object myClassInstance = clazz.newInstance();
