Java Programming Stats-Uses and Pros-Cons
Course Description
Struts addresses many major issues in using vanilla Servlets/JSP to build web systems. It solves the problem of controller complexity by removing the workflow logic from the Servlets, and directing workflow in an XML configuration file. Struts improves on the limited form support in JSP by adding numerous capabilities to form processing including easy validation, easy error display, and the refilling of form input on form retries from a users previous entries. It minimizes the complexity of JSP pages, by integrating with the JSTL tag library, and additionally supplying a very extensive and flexible set of custom tag libraries for many of the standard operations needed in JSP pages. This course will get you up to speed with Struts in a very short time. It includes all the important concepts, and hands on labs that will have you building working Struts applications in no time flat. In addition, this course covers how to extend the Struts framework to fit your unique needs. All labs are done using the RAD Development Environment, and the lab instructions include detailed directions on using RAD and the RAD wizards and tools. Course Length: 3 Days Course Tuition: $1290 (US)

Prerequisites
Suitable for programmers with some previous experience in working with Java and Object-Oriented (OO) programming.

Java Programming Uses & Stats

Java Programming is Used For:

Android & IOS Development Software Products Video Games Desktop GUI's

Difficulty

Popularity

Year Created

1995

Pros

Most Commonly Used:
According to Oracle, three billion devices run on Java. And, because of its real-world applications, it consistently ranks at the top of the TIOBE Programming Community Index.

Great Career Choice:
Some of the fastest-growing salaries in the U.S. in 2018 are for Java developers. (Glassdoor)

Android Apps Development:
Developers predominatly use their Java skills in building apps for Google's Android. The Android platform is the number one mobile paltform in the world

It Can Run On Any Platform:
Java can compile on Windows and run the same compiled file on Linux, Windows and Mac.

Great Supporting IDE's:
Over the years, coding in Java has become simpler with the introduction of open source development tools, i.e. Eclipse and NetBeans that use Java capabilities for debugging.

Cons

Uses a Lot of Memory:
Performance can be significantly slower with Java and more memory-consuming than natively compiled languages such as C or C++.

Difficulty in Learning:
Learning Java can be a bit challenging if you are a beginner. However, once you get the hang of Object Oriented Programming and a decent grasp of the syntax, you will be well on your way.

Slow Start Up Times:
There is quite a bit of one-time initialization done by JDK classes before compiling as well as loading classes and verification (making sure code doesn't do evil things, all of which takes longer that some other languages such as C.

Verbose and Complex Code:
Long, over-complicated sentences make code less readable and scannable. Compare to let's say Python, we can see how clear Python code appears: It doesn’t require semicolons; uses “and,” “or,” and “not” as operators instead of Java’s “&&,” “||,” and “!”; and generally has fewer bells and whistles such as parentheses or curly braces.

Commercial License Cost:
Companies have to prepare for the changes that Oracle will institute in 2019 . Today, the current version of Java is free and available for redistribution for general purpose computing. However, If you are a DEVELOPER, Oracle recommends you review the roadmap information for Java SE 8 and beyond and take appropriate action depending on the type of application you develop and your distribution mode.

Complimentary Skills to have along with Java Programming

- If you are an experienced Java developer, learning a complimentary language to Java should come much more naturally. As an example JetBrains recently created the Kotlin programming language which is officially supported by Google for mobile development. Kotlin compiles to Java bytecode and runs on the JVM; it's purported to address many of Java's shortcomings...
