Intermediate Java 8 Programming

Bascom Bridge’s Intermediate Java 8 Programming training course prepares graduates of our Beginning Java Programming class (and those with equivalent expertise) for the next level of Java programming.

This course goes well beyond the basics of Java and OO programming to cover UML, Design Patterns basics, and using composition vs. inheritance. Attendees learn advanced Java topics such as inner classes, the reflection API, and functional programming with lambdas and streams. Finally, students learn how to use useful tools for day-to-day programming such as JUnit, build tools, and logging frameworks.

JAVA 8 TRAINING OBJECTIVES

All students will:

• Solidify Java foundational knowledge, including the important contracts of class Object
• Understand the uses and consequences of inheritance and composition, and reinforce the role of interfaces
• Reinforce fundamental OO principles such as cohesion, coupling, and polymorphism
• Use the JUnit testing framework and become fluent in writing assertions to verify correct program behavior
• Gain familiarity with UML modeling in class diagrams and sequence diagrams
• Use advanced techniques for object creation, including factories and singletons
• Use established design patterns for object composition, including Strategy, Decorator, and Facade
• Write and use generic classes and methods
• Learn the use cases for inner classes and refactor existing code to use them when appropriate
• Create and use custom annotations
• Be familiar with reflection and how to use it
• Understand the role of functional interfaces introduced in Java 8
• Understand lambda expressions and method references, and use them to pass behavior (methods)
• Use the Stream API to perform complex processing of collections and other input sources
• Learn the new Date/Time API and use it to solve date-oriented business problems
• Use Javadoc to write professional-grade API comments for your classes
• Understand build tools such as Ant and Maven, and how to manage application dependencies
• Write appropriate log statements in your code and configure logging with Log4j

JAVA 8 TRAINING PREREQUISITES

Students must be able to write, compile, test, and debug simple Java programs, using structured programming techniques, strong data types, and flow-control constructs such as conditionals and loops. Our Beginning Java Application Development class is recommended.

JAVA 8 TRAINING MATERIALS

All students for this Java training course receive a copy of Manning’s Java 8 in Action: Lambdas, Streams, and functional-style programming, which is used as the instructional guide for the course, as well as related courseware.

SOFTWARE NEEDED FOR EACH PC:

• Core 2 Duo or faster processor with at least 3GB RAM
• Any operating system that supports Java 1.8 or later
• JDK 8 (7 could be accommodated upon request but would require some topics to be dropped for compatibility reasons)
• The Java tool the students are likely to use after the class (Eclipse is recommended, but IntelliJ IDEA, IBM RAD, NetBeans, and other tools are supported)
• Other free software – please contact us if you have purchased this class
• For classes delivered online, all participants need either dual monitors or a separate device logged into the online session so that they can do their work on one screen and watch the instructor on the other. A separate computer connected to a projector or large screen TV would be another way for students to see the instructor’s screen simultaneously with working on their own.
