![]() ![]() ![]() C was chosen because it was general-purpose, fast, portable and widely used. When Stroustrup started working in AT&T Bell Labs, he had the problem of analyzing the UNIX kernel with respect to distributed computing. In 1979, Bjarne Stroustrup, a Danish computer scientist, began work on “C with Classes”, the predecessor to C++.The motivation for creating a new language originated from Stroustrup’s experience in programming for his Ph.D. It has imperative, object-oriented and generic programming features, while also providing facilities for low-level memory manipulation. The second edition of the book covers the later ANSI C standard.Ĭ++ is a general-purpose programming language. The version of C that it describes is commonly referred to as K&R C. ![]() This book, known to C programmers as “K&R”, served for many years as an informal specification of the language. In 1978, Brian Kernighan and Dennis Ritchie published the first edition of The C Programming Language. The resulting definition, the ANSI standard, or “ANSI C”, was completed late 1988. In 1983, the American National Standards Institute (ANSI) established a committee to provide a modern, comprehensive definition of C. In 1978, Dennis Ritchie and Brian Kernighan published the first edition “The C Programming Language” and commonly known as K&R C. C language was invented for implementing UNIX operating system. C programming language features were derived from an earlier language called “B” (Basic Combined Programming Language – BCPL). ![]() The C programming language is a structure oriented programming language, developed at Bell Laboratories in 1972 by Dennis Ritchie. Java powers set-top boxes, printers, Web cams, games, car navigation systems, lottery terminals, medical devices, parking payment stations, and more.4 billion Java Cards are manufactured each year.31 times more Java phones ship every year than Apple and Android combined.930 million Java Runtime Environment downloads each year.It’s amazing to know that there are around 3 Billion devices that run Java. Sun Microsystems released the first public implementation as Java 1.0 in 1995. Later the project went by the name Green and was finally renamed Java, from Java coffee.Gosling designed Java with a C/C++-style syntax that system and application programmers would find familiar. James Gosling, Mike Sheridan, and Patrick Naughton initiated the Java language project in June 1991.Java was originally designed for interactive television, but it was too advanced for the digital cable television industry at the time.The language was initially called Oak after an oak tree that stood outside Gosling’s office. It is intended to let application developers “ write once, run anywhere ” (WORA). Java is a general-purpose computer programming language that is concurrent, class-based, object-oriented, and specifically designed to have as few implementation dependencies as possible. Since February 2017, Michael Kölling and most of the BlueJ team work at King’s College London, as it can be seen on BlueJ version 4.0.0’s splash screen. In March 2009, the BlueJ project became free and open source software, and licensed under GNU GPL with the classpath exception. Object-oriented concepts (classes, objects, communication through method calls) are represented visually and in its interaction design in the interface.īlueJ is currently being maintained by a team at the University of Kent, Canterbury, England – where Kölling used to lecture. This interaction facility, combined with a clean, simple user interface, allows easy experimentation with objects under development. BlueJ implements the Blue environment design for the Java programming language.īlueJ was developed to support the learning and teaching of object-oriented programming, and its design differs from other development environments as a result.The main screen graphically shows the class structure of an application under development, and objects can be interactively created and tested. BlueJ was an integrated system with its own programming language and environment. BlueJ is an IDE (Integrated Development Environment). The development of BlueJ was started in 2000 by Michael Kölling and John Rosenberg at Monash University, as a successor to the Blue system. ![]()
