When we talk about programming, those who are not familiar with this topic will probably not understand much. Java is one of the most popular programming languages in the world. in this article, we will know what Java is and we will mention several reasons why we should learn it.
Today, all or almost all of us have ever heard or used Java, and now it is almost everywhere, so in this short article we are going to talk about what Java is and why it is important to learn it.
Java is an object-oriented programming language whose version 1.0 was published by the company Sun Microsystems in 1995. Currently, you will see that it is owned by the Oracle company, this is because it bought Sun Microsystems in 2009-10.
And this is possible because it has a JVM or Java Virtual Machine that provides portability to the language since today there are JVMs for different architectures for all platforms.
JDK has a compiler that takes our Java code and validates the syntax, if the compiler finds an error in our code it will show us a message and if everything is fine the compiler will create a file with byte code. Class, this file will be executed by the JVM.
Until 2016 the latest stable version is Java Standard Edition 8, which was launched in 2014, it is a language derived from C has a syntax very similar to this and in terms of its structure, the Java language starts with packages, within which are the classes and within these are the methods, constants, variables, among others.
Little History Of Java
The origin of the Java name is not clear, although it is attributed to a type of coffee that was available to a coffee shop near the workplace of the team that developed it (perhaps keeping them awake during long nights of work?).
Java was born in 1991 with the name “OAK”, later changed by Green for legal problems(the name was already registered by another company), and finally with the current name JAVA.
The aim of java was to create a programming language similar to C ++ in structure and syntax, strongly oriented to objects, but with its own virtual machine. This was done under the principle, of being able to be used under any architecture “Write Once, Run Anywhere (write it once, run it anywhere)”.
In 1992, the green project was presented, with low-level prototypes. Between 1993 and 1994 we worked to present a functional prototype (hot ava) where all the potential that JAVA can offer is seen.
In 1995 finally, the alpha version of java is presented, and a year later in 1996, the first JDK (JDK 1.0) is released. The development of it from then on is unstoppable, new packages and bookstores are presented to the present.
Why learn it
There are multiple reasons why it is good to learn to program in Java, There are some of the many reasons to program in Java.
- It is within the languages most used today and runs on almost all platforms that are in the market.
- If you want to start developing on Android, it is an important base that you need and must learn.
- There are great support, documentation and its communities to which you can go if you need help to better understand the language.
- it also has a series of libraries (native and third-party) that extend their functionalities, from manipulating Office files to recognizing fingerprints and much more.
- it is not a complicated language as you might think since it is a type of object-oriented programming, understanding basic aspects of this type of programming, the learning of Java will be intuitive.
- It is safe, JVM offers us a lot of security against infiltrations of third parties or viruses.
- it is designed to create highly robust and reliable software, for it provides numerous checks during compilation and at run time, it has a garbage collector that eliminates the need for explicit memory release.
