Java is an object-oriented programming language owned by Oracle. It was created in 1995 by Sun Microsystems. Today, this language is widely used in the professional world, it has built its reputation on its excellent portability: a program coded with Java runs on Mac, Linux and Windows.
In Java, we can develop different types of software applications:
Application in the form of a console or window.
A small application downloaded when visiting a website (otherwise known as an applet).
Mobile development (with J2ME)
Java offers a wide range of application development possibilities.
Beyond the fact that Java is compatible with several operating systems, it has another interesting advantage: Java’s syntax is comparable to that of C++, which makes it professional and economical. Java was created with the objective of overcoming all errors in the C++ code. C++ contains its share of errors, Java designers have studied these errors and eliminated them.
The advantages of Java
Java provides a large library of routines that manage TCP/IP protocols such as HTTP and FTP. Thus software developed with Java accesses websites as easily as it accesses a local file on the system. The implementation of CGI scripts (Common Gateway Interface) is much more comfortable with Java. The “servlet” mechanism optimizes server-side processing. Using Java is really simple and reliable, it is hard to get easier.
Java was created to make the programs that use it as reliable as possible. The Java design model encourages developers to quickly identify potential problems through dynamic check launches and eliminates situations that would generate errors.
Unlike its C++ counterpart, Java has a pointer model that prevents any risk of memory overwriting and data corruption. In this because Java is an object-oriented program: it is focused on the data (objects) and interfaces of these objects, it will naturally focus on the realization of the object rather than on how the object will be realized. This type of object orientation allows you to benefit from software that is more structured and more maintainable later on (scalability).
Java is easily understandable for a novice developer. It is a “high level” computer language where everything can be done automatically, there is no need to worry about managing the memory for example or the pointer.
Java is usable in server and distributed environments (a distributed architecture is contrary to a centralized architecture), it allows to optimize the creation of virus-free systems, even if any system can potentially be infected by a virus.
Neutrality and portability of the architecture
The Java compiler will generate an object file that has a neutral software architecture thanks to the transcription of the code into ByteCode. The ByteCode is then translated into machine language. Therefore, the compiled code can run on many processors. We can therefore find the Java language everywhere.
The Java community is very, very large, so the language is constantly evolving thanks to its strong community of very many contributors.
Companies that have adopted the use of Java in their IT projects appreciate its clear and refined syntax.
Types of web application development
Do you know what a web application is and how it differs from other applications for mobile devices? Web applications are not only designed for smartphones or tablets, but for any computer or mobile internet browser. There are several types of them.
Their classification can be based on how the content of the application is presented. There are 6 types of web applications.
Types of web application
Static web application
The first thing to know about this type of application is that it contains little information and, in general, its content does not change or only slightly.
The development of web applications is usually done in HTML and CSS. There may, however, be animated objects such as banners, GIFs, videos, etc. These applications can be developed with jQuery and Ajax.
Changing the content of static applications is not easy. To do this, you must download the HTML code, edit it, then upload it again to the server.
Two typical examples of static web apps are the professional portfolio and the digital curriculum vitae. Similarly, a company’s home page can be created in a web application to display basic information such as your contact information.
