James Gosling, the founder of Java programming language, developed an entirely new programming language in 1991 which had its sole purpose of programming home appliances that are under the control of computer processors. After 20 years of its use, Java found its utilization in the distributed environments of the Internet, as well as in developing Android applications and internet of things. The Java can also work in the iOS ecosystem but it requires the use of Swift, which is a specially written programming language for the development of iOS applications.
Java’s syntax reminds a lot of C++ programming language, with the strong emphasis on object-oriented programming. Developers use Java for the implementation of standalone applications that can be distributed among servers and clients, but it also has a use in programming of small modules within the bigger application. While the C++ apps can work in a certain environment, Java apps can work in any environment after you had installed the Java Virtual Machine.
The language’s basic principles
Java offers portability which means that a code written in Java is compiled into bytecode which gives the application possibility of running on any network or a client that has JVM (Java Virtual Machine) installed.
When it comes to coding, the JVM ensures integrity – each instruction in the code strictly addresses to a unique data that has no address in the external apps or in OS, which means there is no possibility for fatal errors or application crashes. Applets, which are small parts of the app (buttons, scrolling texts, etc.), offer great flexibility regarding running the coded app much faster than any other languages. However, to run Java app on a platform, the platform requires a virtual machine documentation
Programmers can use JAV SE, Java EE and Java ME platforms for the development. The first one has a purpose in developing simple stand-alone apps, providing all of the APIs required for the development of desktop apps.
The Java Enterprise Edition (Java EE) has its purpose for creating server-side components that are connected to web-based requests. Java ME (Micro Edition) represents a Java’s platform for mobile development which is very popular due to embedded device development.
