3-1-3 Object-oriented Language

Object-oriented languages treat data and data processing (i.e., procedures or methods) as a unified unit called an object, and programs are created using objects. Object orientation is an approach that does not focus on processes (i.e., procedures), but on the data that is subject to processing.

Original textbook callout or table. Source text: • C++ This is an object-oriented language that includes the concepts and functions of object-orientation. It is used for more general purpose than C and has a high level of reusability. • Java This is an object-oriented language that was developed by Sun Microsystems, Inc. in the United States on the basis of C++. The programs (i.e., Java applications) developed with Java support multi-platform in which a program can be executed on different hardware or a different OS as long as in the environment in which JVM (Java Virtual Machine) is installed. Since it does not depend on specific types of computers or OSs, it is used in web applications that run on the Internet and also in distributed system environments. Currently, a compilation method that uses a runtime compiler (JIT compiler) is prevalent. • Java Servlet This is a Java program that is executed on a web server in response to a request from a client. A servlet is a program that is executed on the server side. • Java Applet This is a Java program that is downloaded by a client from a web server and is executed on the client. An applet is a program that is downloaded to the client-side to be executed. • JavaBeans This is a specification for handling a program that is developed with Java as an application component. • VB (Visual BASIC) This is an object-oriented language that was developed by Microsoft. It enables the creation of a program in a visual environment that uses windows and toolboxes. A — p. 213 · Enlarge
