It may instead be marked on the verb (this is especially common in null subject languages). The most basic kind of sentence consists of a single clause; more complicated sentences may contain multiple clauses, including clauses contained within clauses.
In object-oriented programming, a class is a programming language construct that is used as a blueprint to create objects. This blueprint describes the state and behavior that the created objects all share. An object created by a class is an instance of the class, and the class that created that instance can be considered as the type of that object, e.g. a type of an object created by a "Fruit" class would be "Fruit".
Why are using classes in java:Classes, when used properly, can accelerate development by reducing redundant code entry, testing and bug fixing. Another reason for using classes is to simplify the relationships of interrelated data.
