Course Description

  
Intermediate Java and OO Development is a fast paced, 5 - day course suitable for programmers with some previous experience in working with Java and Object - Oriented (OO) programming. It includes a short review of basic Java concepts, and then moves on to a comprehensive coverage of more advanced topics in Java and OO programming to provide participants with a strong grounding in using Java in a sophisticated and productive manner. This course goes well beyond the basics of Java and OO programming and cov ers important topics such as composition, inheritance, polymorphism, interfaces and exceptions, which are all key to creating well - structured OO systems using Java. After coverage of these important areas, it moves on to more advanced topics such as JDBC ( for database access), the Java Collections Framework - including the generics capabilities introduced in Java 5, Java I/O, assertions, inner classes, and the reflection API. Finally it covers useful tools for day - to - day programming such as ant, JUnit and v arious logging frameworks. This course covers far more than an introductory course, and provides participants with a comprehensive understanding of how to use Java's advanced capabilities in a more sophisticated manner. It teaches a number of useful techn iques that enhance productivity and good system design - which Java programmers may otherwise take years to absorb on their own.
Course Length: 5 Days
Course Tuition: $2090 (US)

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...
