Course Description

  
The course goes on to cover all the important capabilities of Spring 2.0/2.5, including using Spring to simplify the creation of a persistence layer with JDBC and/or persistence frameworks like Hibernate, and using Spring's Aspect Oriented Programming (AOP) to program cross-cutting concerns such as transactions and security. Understand the core principles of Spring, and of Dependency Injection (DI)/Inversion of Control. Use the Spring Core module and DI to configure and wire application objects (beans) together Understand and use the complete capabilities of the Core module, such as lifecycle events, bean scopes, and the Spring API. Work with the DAO and/or ORM modules to create a well structured persistence layer with JDBC or Hibernate. Understand and use Spring 2.x's powerful new AOP capabilities for programming cross-cutting concerns across multiple points in an application. Understand and use Spring's transaction support, including Spring 2.x's easy to use tx/aop XML configuration elements, and Java 5 annotations. Understand how Spring MVC works, and how to build well-structured Web applications with it Understand and use Spring Web Flow 2 to define user interface flow in Web applications. Understand the basics of Spring Security, and how to secure Web apps and Spring managed beans with it.

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...
