Building Java / JEE Applications using Eclipse (or IntelliJ)

• How Eclipse is built around SWT, OSGi and plugins
• Working with perspectives, views, editors and actions
• Writing standalone programs and simple JEE components
• Making the most of the support for code generation
• Refactoring and Unit Testing your code within Eclipse
• An overview of writing your own refactoring plug-ins

Converting to Java (Part 1)

• The core Java syntax and type system
• The package hierarchy and classpath
• Similarities in selection and iteration
• Similarities when working with arrays
• Comparing the Java and .NET object models
• Class declarations in Java verses in C#
• Key differences in the use of interfaces

Converting to Java (Part 2)

• Properites as accessors and the JavaBean conventions
• The typesafe enum pattern and its integration into Java
• Using inner classes rather than delegates for event handling
• The theory of compiler checked exceptions and proper usage
• Non-reified generics, type erasure and bounded wildcards
• Creating and decorating your code with annotations
• Using compiler plugins to extend the language

Converting to Java (Part 3)

• Making basic use of the standard collections
• Working with the newer thread safe collections
• Functional programming in Java 8 verses .NET LINQ
• Declaring and working with lambdas and method refs
• Using the streams API as your ‘functional toolkit’
• Idioms for getting maximum performance from streams
• Using streams outside of the standard collections
• Using parallel streams for simplified concurrency

An Overview of the Key Java Libraries

• Investigating types using the reflection library
• Performing file I/O, basic networking and multicasting
• Writing concurrent code using executors and futures
• Working with localized dates and times in Java 8

Building Standard JEE Web Applications

• Deploying WAR’s and EAR’s into a JEE Container
• Writing Servlets and using the Servlets API
• Creating control-based UI’s via JSF and Facelets
• Injecting dependencies via annotations like @Resource

Using the Java Persistence API (JPA)

• How the JPA evolved from tools like Hibernate and Toplink
• The concept of a Persistence Unit and its role in JEE Design
• Creating basic entity classes and building Persistence Units
• Using annotations to define embedded types and many-to-one links
• Using annotations to map collections of basic types and entities
• How entities move between the transient, perisitent and detached states
• Using the EntityManager API to more entities between states
• Writing parameterized queries via JPA-QL and CriteriaBuilder objects
• Combining JPA with Generics to create a universal DAO base class

Dependency Injection In Spring

• Declaring Spring beans via @Component and @Service
• Dependency injection by type using @Autowired
• Injecting by name using @Autowired and @Qualifier
• Specifying the scope of a bean and lifecycle methods
• Cusomizing dependency injection via Spring EL

Building MicroServices via Spring MVC and Boot

• Declaring RESTful services via Spring MVC
• Associating methods with HTTP verbs and MIME types
• Marshalling content to and from XML and JSON
• Cusomizing the response and handling errors
• Accessing the services via an Angular UI
• Injecting services into the REST controllers
• Simplifying database access via Spring Data JPA
• Deploying the application via Spring Boot
• Unit and integration testing the application

Additional JEE Specs and Frameworks

• JAX-RS as a standardised alternative to Spring MVC
• JOOQ as a simpler more performant alternative to JPA
• Writing SOAPy Web Services via JAX-WS and JAXB
• Using JMS to interact with Messaging Servers
• The JTA and managing transactions in JEE
