Whats the difference between a class and an object in Java?
A Java class is a definition or model of an object type. A class has a specific set of fields, methods and constructors with distinct argument types. Any object that fulfills a class definition directly or by inheritance has a set of properties and behaviour that is common to all instances of the class. In this sense, a class is a set of things that are alike. In Java concrete classes also provide a code implementation that can be instantiated to create an object reference. An instance of a class directly fulfills its own definition, it also fulfills any superclass definitions too. The Java Virtual Machine creates static references to classes when it runs a Java program. Classloaders make the public static fields and methods of classes available to the runtime system whether any instance exists or not. When a constructor is called, the class returns an instance of the object it represents. Actions: Follow-up or correct this answer. Submit a new question.
