Like many of you, I love quizzes, too. So, let me get a little quizzical and ask you which computer programming language I am talking about. These are the hints:

  • It is powerful
  • It is object oriented
  • It is general purpose
  • Desktop and mobile, android apps, IoT, games, web applications enterprise applications, embedded systems, network applications, and Big Data processing are just some of the areas in which it is used for development
  • Technologies such as J2EE, Struts, Servlets & JSP, Hibernate, Spring, JMS, and android for mobile applications are based on this language
  • As if these clues weren’t simple enough, here is the best introduction to it: it is used in over three billion devices worldwide!

Well, I know all these clues were no-brainers, which is why I want to tell you why you need to read this blog on the top 20 java courses! If a computer programming language has all these credentials, there can be no stronger reason to take a look at the top 20 java courses.

One perhaps doesn’t need to look beyond these highly encouraging numbers about java, the language that Oracle developed and released in the mid 1990’s. One certain point worth mentioning about java is that its growth looks nowhere like it is going to stall in the near future.

Facts support this assessment:

  • The market for java content management systems is set to reach nearly $3 billion by 2027, as it is slated to grow at an astonishing CAGR of over 10 percent
  • It is still the fifth most popular language among computer professionals, even more than 25 years of its release
  • Since it is used in most current technologies and is popular among companies such as, it is set to rise in stature
  • There is a continuing demand for java programming learning, with this market expected to touch almost $80 million by 2025.

Attractive as these figures are, the good news is that SimplivLearning brings you a lot more to cheer: it offers an amazing range of online courses on java! Without further deviation, let me introduce my pick of the top 20 java courses offered on this platform.
