Course Description

  
This course teaches programming in the Java language -- i.e. the Java Standard Edition platform. It is intended for programmers with experience in languages other than Java, but who may or may not have any previous Java experience. It focuses on procedural and structured coding skills first, and then offers meticulous, in-depth coverage of object-oriented concepts and how to apply them to Java software design and development. The latter part of the course moves from these basic skills into key parts of the Java SE Core API, including collections and logging, and introduces features of functional programming, new to the language as of Java 8, including functional interfaces, lambda expressions, and streams. This revision of the course targets the Java 8 language and Core API. See our course catalog for training explicitly geared to earlier versions of Java, going back as far as J2SE 1.4.2. To read more about different versions of Java and for help deciding on which version of this course to use, see "Java Versions and Terminology Demystified".) Students come to Java from a wide range of backgrounds, and this course is designed to be as flexible as possible over the upper end of that range. Specifically: Experienced C and C++ programmers will find this course a very good fit and if anything will find that they complete it in a little less than the full five-day timeline. Those with experience in languages less like Java, such as Visual Basic, ASP and other Web-scripting languages, and other pseudo-object-oriented languages may need more time in the early going, and this course covers its introductory topics in good depth and offers many optional and "challenge" labs to support this. Less experienced programmers or those coming from non-structured languages -- such as COBOL, PL/1, or 4GL tools -- will probably not cover the whole course in a week, and may want to pursue an abbreviated version at a slower pace. This too is quite feasible, but this audience may also want to consider our Course 102, "Introduction to Java Programming," for a more relaxed pace through the early material.
Course Length: 5 Days
Course Tuition: $2090 (US)

Prerequisites
No prior Java experience is required, but students must be experienced programmers in another third-generation (high-level) language. See the overview for suggestions about pace and scope for different backgrounds.

Java Programming Uses & Stats

Java Programming is Used For:
Android & IOS Development Software Products Video Games Desktop GUI's
Difficulty
Popularity
Year Created

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...
