The simplest example of type introspection in Java is the instanceof [1] operator. The instanceof operator determines whether a particular object belongs to a particular class (or a subclass of that class, or a class that implements that interface). For instance:

These are JSON text files. [9] The application can also export manually selected fragments of a model into separate files with having the .mdf extension and import them back. It can also import files from StarUML 1 which use the .uml format. StarUML can generate HTML, PDF and EJS files do document a model.
Java is a high-level, class-based, object-oriented programming language that is designed to have as few implementation dependencies as possible. It is a general-purpose programming language intended to let programmers write once, run anywhere (), [16] meaning that compiled Java code can run on all platforms that support Java without the need to recompile.

import java.util.*; /*This form of importing classes makes all classes in package java.util available by name, could be used instead of the import declaration in the previous example. */ import java.*; /*This statement is legal, but does nothing, since there are no classes directly in package java.
As many consider that including file content has significant drawbacks, newer languages have been designed without an include directive. Languages such as Java and C# support modularization via an import concept that allows a module to use the assets of another module at a conceptual level; not by including text.
Static import is a feature introduced in the Java programming language that allows members (fields and methods) which have been scoped within their container class as public static, to be used in Java code without specifying the class in which the field has been defined.
