Definitions:<\/strong>
\nA class<\/strong> is a template for multiple objects with similar features. Classes embody all the
\nfeatures of a particular set of objects.<\/p>\n

An instance<\/strong> of a class is another word for an actual object. If classes are an abstract
\nrepresentation of an object, an instance is its concrete representation.<\/p>\n

Object is the more general term, but both instances and objects are the concrete representation of a class.
\nIn fact, the terms instance and object are often used interchangeably in OOP language. An instance of a Car and a Car object are both the same thing.<\/p>\n","protected":false},"excerpt":{"rendered":"
