Java, first released in 1995 by Sun Microsystems, is both a programming language and a programming platform on which many websites and Java-based applications run. Even after hundreds of other programs were developed, Java still happens to be a choice program thanks to the fact that it has been there for two and a half decades and was among the first programs available for most enterprises. It is also easy to use. 

There are thousands of Java developers and many providers are now offering Java online certification training. 30-40% of software is either written in or has Java executing it, over 3 billion devices run on Java, and popular sites like YouTube, Google, Amazon, and eBay run on Java and more developers are preferring it for a number of reasons including:

  • It is platform-independent. Java programs can be executed in any machine with Java Runtime Environment in an approach known as write once, run anywhere (WORA).
  • It uses an object-oriented model
  • It is one of the most secure programs which has evolved over a long time
  • Java has a rich API
  • It is fast and user-friendly compared to other languages. Java has two domains, Core Java and Advanced Java.

Advanced Java Programming

Before we look at Advanced Java, let’s first explore Core Java as it forms the foundation for Advanced Java. Core Java is the fundamental level of Java used in all Java platforms and technologies. Without grasping the full concept of core Java, it may be difficult to apply Advanced Java to applications.

After websites and applications have been built on Core Java, Advanced Java concepts like Servlet programming are applied to enhance their capabilities and make them feature-rich. While the scope of Core Java is limited to just client-side applications, Advanced Java extends beyond to server-side applications. This explains why it has a two-tier structure.

For programmers, Advanced Java is more specialized Core Java where they become experts in domains like networking, web, and database handling, etc. A good Advanced level training endows programmers with practical knowledge in such advanced concepts as REST service creation, JSON parsing, and XML handling, on top of the knowledge they already have in Core Java.

What comes under Advanced Java?

Advanced Java is the next level of programming after Core Java. It covers more advanced concepts and technologies in Java such as database connectivity, Java Enterprise APIs like Enterprise JavaBeans (EJB), Servlet programming including JSP technology, web services, and more.

Some important Advanced Java topics include

  • SQL
  • JDC
  • Hibernate
  • Servlets
  • JSP
  • Struts
  • Spring
  • Soap based and REST full Web services

Why Advanced Java is essential

Advanced Java has some advantages that have made it a must-have skill in programming. I have listed just a few here:

  1. It employs two-tier Architecture. Unlike the one-layer architecture in Core Java, Advanced Java employs a two-layered architecture that runs on both client and server-side applications making it autonomous. For instance, access to J2EE a platform-independent Java-Centric environment that lets developers build and deploy web-based multi-layered applications online.
  2. Also referred to as Java Enterprise Edition (JEE), Advanced Java gives programmers access to a resourceful library from which they will understand the client-server architecture of web applications. This feature is not available in Core Java.
  3. Advanced Java empowers programmers to develop both web and mobile applications. Such skills give them the ability to work with web application servers like Glassfish, as well as navigate the operation of the HTTP protocol.
  4. In Advanced Java, the naming convention follows the pattern of javax.servlet and not java.lang as in Core Java packages. This means that Advanced Java applications run on servers hence web applications.
  5. There are numerous advanced Java frameworks. These include frameworks like struts and spring that facilitate security for webs and apps meant for transactions as used in E-commerce, the financial sector, and the healthcare sector among others.
  6. Without Java Advanced skills, in addition to Core Java skills, coders may find it difficult to handle technologies like Hadoop and cloud services.

Advanced Java proficiencies provide an effective environment for executing Java applications. Additionally, the APIs contained in the Java Enterprise edition includes features like web services, servlet programming, and persistence API used as building blocks for distributed applications.

Best way to learn Advanced Java

For you to start studying advanced Java, you should have mastery of the fundamental concepts of Core Java. This is because Advanced Java has its roots in Core Java hence it would be difficult to grasp the concepts of Advanced Java without first laying a foundation.

Deciding on the best learning method can be determined by a number of factors like the available time, competency level, and study discipline.

For example, while some people can learn Advanced Java through self-study, others can study effectively by following YouTube and Google tutorial videos and taking freestyle coding training. Still, others will learn best by enrolling for an online training course.

Why it is important to enroll for an online course

Given that you now need to have a mastery of complex concepts like J2EE architecture, JSP, and Struts among others, consider pursuing a full Java course that will not only equip you with practical skills but also a recognized credential that will boost your CV as an Advanced Java specialist.

Enrolling for an online training course with a credible learning provider comes with numerous advantages. For starters, you will have access to tutors with various industry experiences and secondly, you will benefit from the tried and industry-tested pool of knowledge offered in the approved curriculum. Considering that, Advanced Java is all about practical skills, institutions tend to have systems that make professionals learn quickly. Compared to the self-study gained from books and YouTube channels, institution training prepares you to have the knowledge and competence that meets industry standards.

To personalize your learning, for every finished module and learned concept, it’s recommended you create a personal project that will help you practice and master that targeted skill.

Finally, learning in an online class environment builds deep interest in students by offering them an environment in which they engage in group discussions and other activities. It also provides an accountability environment that enables you to learn with discipline but without pressure.

The best way to learn Advanced Java is by enrolling in a program in which you will be able to learn by doing.
