Would you like to know more about Java programming language? If yes, you are at the right place. But before discussing Java language any further, it is prudent you first understand who invented it and in which year. The person who is credited with having invented java in 1994 is known as Gosling. Why? He is the one who come up with the Java’s original design and then went ahead and developed the language’s original virtual machine and compiler.
What is Java?
It is a general-purpose programming language that was initially developed by Sun Microsystems, which later merged with Oracle Corporation. Currently, it is the most utilized programming language in the computer industry powering over 3 billion devices and with more than 9 million developers using it. Luckily, due to its popularity and wide adoption, there is a large amount of helpful resources including support communities, libraries, documentation and so on.
As a modern programming language, Java is a concurrent, platform-independent, object-oriented programming language with a neutral architecture and whose programs are highly portable. What does it mean when we say that Java is an interpreted language? It means that Java language bytecode has to pass through the JVM (to be interpreted) before it can run on your hardware unlike for C++ or C programs. Also, Java has an inbuilt automated memory management system. Where did it derive most of its concepts? From C++ and C, although it is a higher level language than both of them.
What is its function?
Originally, java’s goal was to develop ��write-once’ ��run-anywhere’ applications. What does that mean? The applications developed using Java language can predictably and seamlessly run on different computer architectures. On the other hand, C and C++ programs have to be compiled separately per each operating system and hardware architecture of the machine you want to run the program on, thus limiting that application’s portability. However, applications made in Java are saved as bytecode which can be run predictably, consistently and safely on any combination of OS and hardware that supports Java Virtual Machine (JVM) and Java Runtime Environment (JRE).
What are its applications?
Java programming language is used in countless real world applications such as developing Android applications. Other applications like client-server web apps and web apps like e-commerce sites are also programmed in Java, not to mention numerous software development debug environments and tools like Eclipse. Some other areas where Java is employed, albeit in some form, include the big data analytics field where you can find Hadoop tool and the financial industry field where you can find analytic tools, client portals, and trading applications among others. Probably, even the web browser you are using to read this content has huge chunks of java code.
Advantages of using Java
One of the benefits that stand out about it is its ability to work across varying operating systems and platforms. As we saw earlier on, Java applications’ bytecode can be installed and then run on all platforms through JVM. Considering the array of devices currently on the market, Java smoothens things up for developers. Apart from that, Java language has great networking support, great database management, and many reusable software libraries. Better still, it comes along with excellent debug and development environment that makes it easy for developers to code complex applications.

With over 200 videos and 20 hours of content, this online Java training course is designed to provide a solid foundation in Java programming and Eclipse for programmers who are already proficient in another language. Besides learning the basic structure and syntax of the language, you will also learn object-oriented principles and how they are applied in Java applications. In addition, this training course covers more advanced features of the language such as abstract classes, interfaces, generics, packages, and exception handling. Finally, you will learn two foundational API libraries: I/O streams and collections. This online training course is current to Java 7 and uses the Eclipse IDE. If you are a complete beginner with no programming experience, please see our Learn to Program with Java for Complete Beginners courses, instead.

We’ll be working with Hibernate 4.3.5.Final (and applicable updates for Hibernate 5.0), and using Hibernate as a JPA provider for the most part of this course. You’ll be learning the fundamentals and some of the advanced JPA features for object/relational mapping, querying, caching and performance. Everything important that you’re going to experience when you’re persisting Java objects with Hibernate is covered during the lectures itself, with the help of animations and stepping through the code. It will allow you to focus more on the concept and the events happening at runtime at the very same time when you’re learning a concept, rather than waiting for me go through lengths of coding first before I could show you the same result. And then you practice the same concept with all the source code provided to you after each session that has a lab exercise.
