Java New Features Training

Course 939

Duration: 3 days
Labs: Yes
Language: English
Level: Foundation

This Java New Features training course provides hands-on experience with lambda expressions introduced in Java and many other language and library changes. Attendees will fully appreciate functional-style programming and the new idioms made possible by lambda expressions that make their code easier to read and understand. The course then explores the Streams API, which lets you write robust code that processes a collection of data in a declarative way. Attendees will fully appreciate what streams are and how they can use them in their programmes to process data collections concisely and efficiently.

Course FAQs

This course provides hands-on experience with new features added in version 8 and later of the Java programming language. It covers lambda expressions, the new Date and Time API, default methods for interfaces, streams and the associated techniques for processing data in parallel and asynchronously as well as other changes to the language and libraries.

Anyone developing Java applications who has core Java SE skills and wishes to leverage lambda expressions in their code to make it easier to evolve, simpler to understand and more maintainable, as well as anyone who wishes to leverage Java streams in their programmes to process collections of data concisely and efficiently.

The course assumes a background in Java programming with Java 7.

This course is suitable for people who are familiar with core Java programming. It aims to get the attendee to the point where they can take advantage of features in Java and later to:

Pass code as data in method calls and returns
Evolve APIs while maintaining backward compatibility by using default methods
Perform date and time manipulations with the much improved Date and Time API
Instantiate streams and user them to process data
Perform parallel processing with streams
Perform asynchronous processing with streams

This course builds on the basic Java programming constructs. For a person who does not already programme in Java the ideal course is the four-day Introduction to Java Programming Training while for best practices and design patterns one would look at Java Best Practices and Design Patterns Training. There is a specialised course for Java Web Services, Building REST and SOAP Web Services with Java Training, as well as one for Spring and Hibernate, Developing Modern Enterprise Java Applications Using Spring Training.

Approximately 40% of time on the course is devoted to hands-on exercises, allowing you to gain extensive experience with lambda expressions. Exercises include:

Employing lambda expressions in the Execute Around Pattern
Working with different time zones and calendars
Evolving APIs by adding default methods to interfaces
Filtering and slicing data with streams
Employing Collectors for mapping and reducing
Turning a sequential stream into a parallel one
