Course Description

  
Spring is a lightweight Java framework for building enterprise applications. Its Core module allows you to manage the lifecycle of your objects, and the dependencies between them, via configuration metadata (usually XML) and Dependency Injection / Inversion of Control. Its advanced capabilities provide support for JDBC and persistence frameworks like Hibernate (DAO and ORM modules), Aspect-Oriented Programming (AOP module), integration with Java Web technologies (MVC and Web Flow), security, transactions, and more. This course is a new course based on the Spring 3 release. It includes complete coverage of the annotation based approach to configuration and the use of Java-5 capabilities that was first introduced in Spring 2.x, and which has been greatly enhanced in Spring 3. It also provides coverage of the traditional XML-based configuration that can still play an important role in existing and new projects. The course starts with the basics of Spring and in-depth coverage on using the powerful capabilities of the Core module to reduce coupling, and increase flexibility, ease the maintenance, and testing of your applications. It goes on to cover all the important capabilities of Spring 3, including using Spring to simplify the creation of a persistence layer with JDBC and/or persistence frameworks like Hibernate and JPA. It includes coverage of advanced capabilities such as using Spring's Aspect Oriented Programming (AOP) to program cross-cutting concerns such as transactions and security. It provides an introduction to Spring Security v3, its architecture, and how to use it to secure both Web application requests and bean invocations. The course includes integration of Spring with Java EE Web applications, an introduction to Spring's Web MVC, and thorough coverage of Spring Web Flow 2 (which is still the latest version available). Spring MVC is a Web framework based on the powerful Model-View-Controller pattern, and the introduction covers the basics of Spring MVC, and how it supports organizing your Web applications in a highly structured, loosely coupled manner. Spring Web Flow 2 is a Spring framework for defining user interface flow in a Web application. The course includes thorough coverage of Web Flow, including an overview of its capabilities and architecture, defining flows, flow variables and actions, the Unified EL, and flow 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...
