Java is one of the most common
languages being used by developers around the world. Although some of its uses
have been replaced by newer languages such as Rust and Python, Java continues
to be resilient in many fields such as data science, web development, and
applications. For any modern developer who wants to get into a field like
web-development or full-stack development, learning Java is a must. Of course,
it is not a difficult thing to get into Java. There are several training
courses available online made by reputed companies. These courses help
interested candidates to learn the basic ideas of Java or get into advanced
applications of the language.
WHY DO WE USE JAVA?
Java itself is used in data science.
The entirety of Hadoop and its related tools have been written in Java.
Therefore, there is a huge demand for Java architects in the field of data
science to help companies make use of data science tools such as Apache Spark,
Trident, and Hadoop. It is a great tool to have if you are looking forward to
conducting data analysis and make use of distributed networking to build
machine learning models.
In the web development industry,
Javascript has huge applications in building networking models and dynamic web
pages. Javascript based languages such as Express, Node, and React are
extremely helpful to make interactive websites. They are very useful tools in
full-stack development. While most languages can be segregated as a front end
or back end, Javascript is unique because languages such as Node can work on
the back end, and React can power the front end.
SOME POPULAR JAVA CERTIFICATIONS
Although many companies provide
online Java training resources, only a few are worth
noting. Candidates should not be swept by the huge amount of choices in the
market. When it comes to getting credible information, they should rely on
trusted sources.
To begin with, Oracle Certified
Professional Java Programmer is a certification course authorized by OCA. This
is a great course for industry veterans who have worked with Java programs
before. If the individual has the adequate work experience and knowledge about
the fundamentals, they can get some training before applying to get certified.
The exam tests the practical skills of the candidate as well as the rudimentary
ideas and principles of Java.
Web Content Developer is another
certification for the veterans. It helps candidates who want to make use of
Javascript to build web applications and dynamic pages to show their skills and
get certified. This is the first choice of most individuals who have passed the
OCPJP certification.
Hortonworks Apache Spark Developer
is a course that helps programmers to present their knowledge in Java to build
data science models. They can make use of Java-based Apache Spark to transform,
manipulate, and process some data set and build a practical application. The
interested candidates should also have some idea about core concepts such as
distributed storage, cloud computing, and data query.
BENEFITS OF THE CERTIFICATION
Learning Java opens up several
industries for candidates to build a career in. It helps candidates to gain
access to popular fields such as data science and web development. These fields
are the creamy layer of the IT industry because most of the jobs stem from
them. Java itself is an incredibly versatile language with a large community
working behind it. With proper networking skills, candidates can take help from
peers and senior professionals whenever they have a problem.
Java provides the necessary skills
to the employees so that they can fill all kinds of job positions. They can
apply to become Hadoop developers, web developers, data scientists and
analysts, and Spark professionals. In the web development scene, they fit
perfectly as security professionals, networking experts, and back end
programmers. Candidates proficient in React can also work as front end
developers, even independently. There is a huge demand for the language as
well. That is why the average salary of Java architects working in data science
is about $125,000 every year. Even freelancing web developers earn handsome
amounts by working on projects and managing the entire framework of a website.
All that said, Java can be tough
when it comes to building applications on your own. Most Java professionals
work in teams. Therefore, any interested candidate should focus on working on
community projects on Github before heading to kickstart their
career. Having some practical knowledge is a great bonus for anyone who wants
to become a Java developer.
