Java has been a versatile language medium that could be used anywhere from enterprise application systems to mobile Apps, ever since it was unleashed in early 1990s.
The viability of this globally most-used programming language is undebatable in the contemporary as well as the impending enterprise computing age. Java developers, for this very reason, will be on demand and will continue to have significant roles in the industry for a long time.
Though Microsoft .NET is a great language which could be considered as the better clone of Java, it does possess a strong drawback of getting locked in to the vendor software. This is a prime reason why different businesses do not adopt this particular platform.
A Java developer must have absolute clarity on fundamental object oriented designs, to start with. This includes comprehending what is an object, a class, inheritance, polymorphism, abstract class, operator overloading and so on.
It is imperative that the developer learns the various concepts by his / her own coding practice as it aids in interpreting the right places to implement these designs in business.
Java is indispensable in the field of mobile applications due to Android. As such applications are being targeted by many startups around the world, sound skills in Java can yield a great future.
Though learning web programming in Java through servlets and JSPs is vital for a developer, getting smarter with Java messaging services, networking and swings can help him evolve.
Strong knowledge of the fundamentals is crucial for learning and working with advanced concepts like Hibernate, Structs, Spring etc. Java, being network-savvy as well as secure at the same time, is an integral part of popular contemporary enterprise applications such as Twitter, Amazon, Linkedin and Google and the future of Java and its developers is evident therefore.
Another aspect worth a discussion is the classic debugging / troubleshooting know-how of a Java developer. While these skills come through with a lot of reading and experience, there are excellent developer tools like Takipi, Sentry, Raygun and the likes available to identify and crush the bugs before they act up. These tools can capture exceptions, detect and report defects and log events while being easily installable with minimum overload.
Java is one of the most taught languages in the academic settings in order for the students to understand object oriented programming and other related concepts. This implies that there will be lots of students interested and rather proficient in coding Java even before they graduate. They enter into the workforce after graduation with some or a lot of knowledge in Java development.
With the amazing and neat new features of Java 8 such as Lambdas and accumulator classes, Java will remain relevant for the next many years and the need for Java developers will ever be on the rise.
Some of these crisp new features provide simplification of the coding process with the developer actively doing nothing more than an installation and becoming familiar with the syntax, so as to benefit from them.
