  2. Interface-based programming - Wikipedia

    en.wikipedia.org/wiki/Interface-based_programming

    Java till Java 8 merely had a package system, but Java software components typically consist of multiple Java packages – and in any case, interface programming can provide advantages over merely using Java packages, even if a component only consists of a single Java package. Interface-based programming defines the application as a collection ...

  3. Java (programming language) - Wikipedia

    en.wikipedia.org/wiki/Java_(programming_language)

    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. [17]

  4. Java Foundation Classes - Wikipedia

    en.wikipedia.org/wiki/Java_Foundation_Classes

    The Java Foundation Classes are comparable to the Microsoft Foundation Class Library (MFC). JFC is an extension of the original Java Abstract Windowing Toolkit (AWT). Using JFC and Swing, an additional set of program components, a programmer can write programs that are independent of the windowing system within a particular operating system.

  5. Class (computer programming) - Wikipedia

    en.wikipedia.org/wiki/Class_(computer_programming)

    The various object-oriented programming languages enforce member accessibility and visibility to various degrees, and depending on the language's type system and compilation policies, enforced at either compile time or runtime. For example, the Java language does not allow client code that accesses the private data of a class to compile. [12]

  6. Composition over inheritance - Wikipedia

    en.wikipedia.org/wiki/Composition_over_inheritance

    Due to the C++ language not having a dedicated keyword to declare interfaces, the following C++ example uses inheritance from a pure abstract base class. For most purposes, this is functionally equivalent to the interfaces provided in other languages, such as Java [ 4 ] : 87 and C#.

  7. Object-oriented programming - Wikipedia

    en.wikipedia.org/wiki/Object-oriented_programming

    In the 1970s, the first version of the Smalltalk programming language was developed at Xerox PARC by Alan Kay, Dan Ingalls and Adele Goldberg. Smalltalk-72 included a programming environment and was dynamically typed, and at first was interpreted, not compiled. Smalltalk became noted for its application of object orientation at the language ...

  8. Swing (Java) - Wikipedia

    en.wikipedia.org/wiki/Swing_(Java)

    Swing is a component-based framework, whose components are all ultimately derived from the JComponent class. Swing objects asynchronously fire events, have bound properties, and respond to a documented set of methods specific to the component. Swing components are JavaBeans components, compliant with the JavaBeans specification.

  9. Component-based software engineering - Wikipedia

    The system can be designed visually with the Unified Modeling Language (UML). Each component is shown as a rectangle, and an interface is shown as a lollipop to indicate a provided interface and as a socket to indicate consumption of an interface. Component-based usability testing is for components that interact with the end user.
