History of the Java programming language
Java Programming Language is one of the leading programming languages among high level programming languages, which was developed in 1995 by Sun Microsystems and by James Gosling, Mike Sheridan. Sheridan) and Patrick Naughton. The original purpose of the Java programming language was to be used in cable TV. But over time, that goal became the creation of a versatile programming language, capable of running on different operating systems.
The Java programming language, first called Oak and then Green, was developed as a project by Gosling et al. Eventually, however, they chose the name for their new programming language because of their particular interest in Java coffee (Java). Java is the name of an island in Indonesia that is a special type of coffee produced by this island and is known as “Java Coffee” or Java Coffee (Jv Coffee).
Write once, run everywhere
The most important feature and philosophy of the Java programming language is: Write Once, Run Everywhere or Write Once, Run Anywhere (WORA for short). Using the Java programming language, computer programs are written only once, and to run them, you do not need to recompile them to be compatible with different operating systems and hardware. Hence, this programming language has grown tremendously over the years and is now used as the main language in the development of programs related to computer-like systems.
Since 1995, applications written in Java, on various operating systems and on machines similar to computers (such as printers, ATMs, parking meters, CCTV cameras, mobile phones, modems, Routers, toll booths, etc.) have been used extensively, to the point that, according to 2014 statistics, more than 3 billion devices (machines) now use Java. In this respect, the Java programming language holds the record and has the most variety of executable environments among programming languages.
In fact, programs written in Java are translated into an intermediate language, called bytecode, when compiled, and the content is stored in files with a class extension. be. Programs translated into bytecodes are independent of the computer architecture and can be run on any operating system. Because for each operating system, an executable program called Java Virtual Machine (Java Virtual Machine) (JVM for short) is implemented by Java developers and allows the bytecode as an application under the system Destination agent, run. This is similar to the model implemented in the Microsoft .NET Framework and the Microsoft Intermediate Language (MSIL).
Applications of the Java programming language
In particular, after the introduction of the Android operating system (Android) for smartphones and tablets, and the introduction of Java as the main language for the development of applications under Android, the general popularity of using it, increased and this language has a special place Terry achieved among other programming languages. On the other hand, many scientific and technical programs have been implemented using Java, which have many applications in various fields of industry and academic research. Among them, we can mention Weka software (WEKA) which is a tool for data mining and is fully implemented in Java programming language.
In addition to implementing applications to run on PCs and smartphones, many websites have used the features available in Java to implement a dynamic structure, and today, Java is used in more than 14% of the entire web. Websites of the world, after PHP, is the most widely used programming language in the field of web programming and implementation of dynamic website.
A set of Java programming tutorials
A set of 23 Java programming instructional videos introduces the audience to the Java programming language and its various features. In this training series, all topics are taught by stating and explaining theoretical foundations and then by implementing practical examples step by step, and in this regard, it is very effective in creating a deep knowledge in the field of programming. Specifically, this tutorial uses the latest version of the Java programming language (Java 8) and discusses object-oriented programming (along with theoretical foundations) and graphical interface programming (GUI design and programming). Have also been discussed.
In this tutorial, version 8 of Java is used and the NetBeans IDE environment (version 8.0.2) is used to implement projects and applications. In addition to discussing the various components of Java programming, in particular, the new features introduced in the eighth version of Java are emphasized. Like other Faradres trainings, during this training, all the programs and projects discussed in the lessons have been created and implemented step by step and completely from the beginning.
One of the important features of this training is to make it possible to get acquainted with advanced programming methods (especially object-oriented programming and its basic concepts). Because along with the practical topics discussed in this training, the theoretical, conceptual and theoretical foundations of advanced programming methods have also been discussed, which can help the audience of this training, in a deeper understanding of the concepts related to Advanced programming, especially object-oriented programming, help.
