The modified object is often a class, a prototype, or a type. Extension methods are features of some object-oriented programming languages. There is no syntactic difference between calling an extension method and calling a method declared in the type definition. [1] Not all languages implement extension methods in an equally safe manner, however.
Extensible programming systems should regard programs as data to be processed. Those programs should be completely devoid of any kind of formatting information. The visual display and editing of programs to users should be a translation function, supported by the extensible compiler, that translates the program data into forms more suitable for ...
java is the Java runtime launcher, a type of SDK Tool (A command-line tool, such as javac, javadoc, or apt) -classpath D:\myprogram sets the path to the packages used in the program (on Linux, -cp /home/user/myprogram ) and
Extensibility is a software engineering and systems design principle that provides for future growth. Extensibility is a measure of the ability to extend a system and the level of effort required to implement the extension.
In object-oriented programming, the open–closed principle (OCP) states "software entities (classes, modules, functions, etc.) should be open for extension, but closed for modification"; [1] that is, such an entity can allow its behaviour to be extended without modifying its source code. The name open–closed principle has been used in two ways.
Among other developments was the Common Lisp Object System, which integrates functional programming and object-oriented programming and allows extension via a Meta-object protocol. In the 1980s, there were a few attempts to design processor architectures that included hardware support for objects in memory but these were not successful.
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.

A JAR ("Java archive") file is a package file format typically used to aggregate many Java class files and associated metadata and resources (text, images, etc.) into one file for distribution. [4] JAR files are archive files that include a Java-specific manifest file. They are built on the ZIP format and typically have a .jar file extension. [5]
