BlueJ is an integrated development environment (IDE) for the Java programming language, developed mainly for educational purposes, but also suitable for small-scale software development. It runs with the help of Java Development Kit (JDK). BlueJ was developed to support the learning and teaching of object-oriented programming, and its design ...
This is called a class, or object (an object is created based on a class). Each object serves a separate function. It is defined by its properties, what it is and what it can do. An object can be part of a class, which is a set of similar objects. Information hiding: The ability to protect some object components from external entities.
The Qi4j programming environment offers a way to express Role method injection into Java objects. [8] Java 8 default method on interfaces can be used to implement Roles in a typesafe way. In the above money transfer use case, for example, the Role methods in the SourceAccount and DestinationAccount enact the actual transfer.
Greenfoot is an integrated development environment using Java or Stride designed primarily for educational purposes at the high school and undergraduate level. It allows easy development of two-dimensional graphical applications, such as simulations and interactive games.
Focused on software quality, Eiffel is a purely object-oriented programming language and a notation supporting the entire software lifecycle. Meyer described the Eiffel software development method, based on a small number of key ideas from software engineering and computer science, in Object-Oriented Software Construction. [18]
Class-responsibility-collaboration (CRC) cards are a brainstorming tool used in the design of object-oriented software. They were originally proposed by Ward Cunningham and Kent Beck as a teaching tool [1] but are also popular among expert designers [2] and recommended by extreme programming practitioners. [3]
Object-Graph Navigation Language (OGNL) is an open-source Expression Language (EL) for Java, which, while using simpler expressions than the full range of those supported by the Java language, allows getting and setting properties (through defined setProperty and getProperty methods, found in JavaBeans), and execution of methods of Java classes.
A key goal of the Object-Oriented approach is to decrease the "semantic gap" between the system and the real world by using terminology that is the same as the functions that users perform. Modeling is an essential tool to facilitate achieving this goal . Abstraction. A goal of most software methodologies is to first address "what" questions ...
