The Java language

Initially, James Gosling's Java language was called Oak; the lawyers pointed out that "oak" had already been recorded by others, so something else was chosen to give the language a name.

The search method went from finding a suitable name for the language to one that wasn't; however time has disproved the method given Java's success.

After some time, names suggested and then withdrawn, legend has it that the name Java was found in a coffee break in front of a hot and steaming cup of coffee from which the Java logo also derives.

The Java language

Introduction to the Java language

The goal of the Java language has always been to create applications that adapt to various electronic devices; bypassing all the typical limitations of languages such as C and C ++ but maintaining the characteristics. 

This choice also proved successful; because many programmers later started using the Java language, aided by their familiarity with their C background. 

Networking

A full range of ready-to-use standard networking libraries that weren't included in other languages gave the language a boost on the internet. 

Other languages had to remedy this by integrating third-party libraries and not always with little difficulty and this made Java more attractive to programmers.

Netscape in 1993 was the first browser to integrate into the JVM (Java Virtual Machine) hosting the first Applets "small applications written in Java language for the client side" when JavaScript very popular today was not even under development.

Is the Java language interpreted or compiled ?

Java is an OOP programming language acronym for "object oriented programming"; the code is interpreted but not compiled and this makes the portability of the software useful "write once run anywhere". 

The source code written in Java language is processed by the compiler class; although the name seems to refer to the compilation, it does not perform this task! 

The Java code is not translated into binary but into intermediate code: the bytecode; the latter is interpreted on the fly by the java virtual machine interacting with the operating system and the underlying hardware.

The origins of computer programming

Modern computers can process large amounts of data. Before the current computers we can only refer to the analytical machine of Charles Babbage; This machine performed calculations thanks to the rotation of gear wheels. Countess Ada Lovelace participates in the creation of Charles Babbage's analytical machine by decoding the language to make it work; US Department of Defense dedicates the ADA programming language in the name of the Countess.  The role of women in computer science  Apparently, the position of women in the history of computer programming seems to cut out only a marginal role; in reality, it is not so! As already mentioned in the previous paragraph; without the contribution that Countess Ada Lovelace left to the world of information technology; this science could be decades behind. The origins of computer programming languages  The origins of programming languages were determined by a mechanical and mostly experimental approach; with reference to the an...

Learn to use the computer

Many people use the PC every day to connect to the network and to work but without knowing what the computer is and wondering how this is possible. We put a computer to work every time we buy with a credit card, withdraw from an ATM, pay a postal order, buy a train ticket, play video games and many other things. Understanding how the PC works inside is too much but starting from its components and the origins of  IT is already a good start. Learn to use the computer Basic computer components The computer is made up of several electronic components on printed circuits that interact with each other via micro pulses; if you want to learn how to use the computer, the main components of a PC are: A central processing unit (CPU); the "processor" used to process active processes on the data before outgoing transmission. RAM memories (random access memory) in which the bytes for processing are loaded; it is the dynamic memory of the computer and it is volatile; A graphics processing...

Introduction to the JavaScript language

In this introduction to the JavaScript language we discover one of the programming languages that has changed the concept of understanding the Web. The added value of JavaScript to the HTML code is to make the Web page dynamic in its interactions with the user. JavaScript is a client-side web programming language. Web 2.0 was born with the JavaScript language. The advantages of the JavaScript JavaScript or "JS" in its abbreviated form; is the most widely used client-side scripting language on the web. The advantage of the JavaScript is that it can be interpreted by almost all browsers; while what has allowed a strong expansion is the availability of many frameworks and libraries that can be easily integrated into scripts. The language is unique in its kind for data exchange thanks to the asynchronous AJAX (Asynchronous JavaScript and XML) functions that allow you to interact with users without reloading web pages and to exchange data in JSON (JavaScript Object Notation) for...
