The object oriented programming concept was introduced in the late 1960s but now it has become the most popular approach to develop software. In object oriented programming, the software is developed by using a set of interfacing objects. An object is a component of program that has a set of modules and data structure. The modules are also called methods and are used to access the data from the object. The modem technique to design the program is object-oriented approach. It is a very easy approach, in which program is design by using objects. Once an object for any program is designed, it can be re-used in any other program. Now-a-days, most popular and commonly used object oriented programming (OOP) languages are C++ & JAVA.

1. C++

C++ was developed in early 1980s by Bjarne Stroustrup. It is an object- oriented programming (OOP) language. It is an extension of C programming language. C++ includes all the elements of the C language plus it has additional features for working with objects, classes, events and other object-oriented concepts. Most of the application programs, such as word processing and spreadsheet program are developed in C-H-. It can also be used to develop database systems and web applications.

2. JAVA

Java is another powerful object oriented-programming language. It ç5 developed in 1991 by Sun Microsystems. It is very similar to C++ but it is especially used for web page designing. The Java programming language is a general-purpose language, Like C & C++, any kind of problem can be solved in this language.

The Byte Code Interpreter program is used to run the Java program. This program is also called the Java Virtual Machine. The byte-code interpreter is not dependent on any specific computer. It can be used on any computer.

Java applets are developed in Java language. A java applet is a small Java program that runs inside another program such as web browser. Both -Internet Explorer and Netscape Navigator can run Java applets. The Java applets are embedded into web pages to rotate images, for animations and to access databases on the Internet.

The term visual programming refers to creating or developing Windows-based applications or graphical user interface applications. The visual programming languages, sometimes called fifth-generation languages. These are object-oriented programming languages. These languages provide visual or graphical interface facilities to develop GUI applications. The most popular and widely used visual programming language is Visual Basic (VB).

Visual Basic (VB)

Visual Basic is an object-oriented programming language. Visual Basic was developed by Microsoft Corporation of USA in 1991. It is used to create application programs that can only be executed into Windows operating system. The commands of application programs are appeared on the screen in the form of small buttons or images and pull down menus etc. Each of these is referred to as object.

Visual Basic has large number of built-in controls or objects displayed into its toolbox during program designing. Using these objects, the programmer can design the application very easily and rapidly.
