Course Description

  
The five-day timeline of this course explicitly targets less experienced programmers, providing them with a thorough step-by-step introduction to Java programming. It lays a firm foundation for further study of Java. There are a large number of example programs and many labs. An important thrust of this course is to teach programming from an object-oriented perspective. It is often difficult for programmers trained originally in a procedural language to start "thinking in objects." This course introduces object-oriented concepts very early, and Java is developed in a way that leverages its object orientation. Most of the course emphasizes simple classes without inheritance. The last chapter introduces inheritance and polymorphism, along with interfaces and collections. This revision of the course targets the Java 8 language and Core API
Course Length: 5 Days
Course Tuition: $2090 (US)

Prerequisites
Good general problem solving skills. Some previous experience programming in a procedural language is essential.

Java Programming Uses & Stats

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

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...
