Whenever we decide to start learning of any programming language, there are couple of requirements we need to go through. But if you decide to learn Java, it seems that you are a bit lucky as there are not too much of the requirements you have to meet. To my mind, the only and the biggest requirement is to be dedicated to learn it. It would be beneficial if you have an overview of Object Oriented Programming (OOP), but if not, it is not a big deal.
There might be another question why should we learn Java and not any other Object Oriented Programming language? Even if we don’t go into the deep details of specifics of few object oriented programming languages, there is the first answer that always comes up to our minds: Java is platform independent language. What does it mean? It means that we can write and run Java program on every machine: linux, windows, mac. The main idea of Java programming language is: Write once, run everywhere”.
Another reason, why should we learn Java is that this language is “rich” with its APIs. For example, Java has huge support of networking, Input/Output, Database connections and many other APIs, which comes together with JDK (Java Development Key) installation. Together with these, there are huge number of free libraries for Java language.
Together with the fact that Java is free, it has the most sophisticated documentation which helps developers to get known with the details of each class or library. Javadoc, makes the learning process easy and fast.
