This Java New Features training course provides hands-on experience with lambda expressions introduced in Java as well as many other changes to the language and libraries. Attendees will get a full appreciation of 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 powerful code that processes a collection of data in a declarative way. Attendees will get a full appreciation of what streams are and how they can use them in their programs to process collections of data concisely and efficiently.

Anyone developing Java applications who has core Java SE skills and wishes to capitalise on the addition of lambda expressions and streams library in Java to create less error-prone and simpler concurrent programs.

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 programs 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 backwards 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 program in Java the ideal course is the four-day Introduction to Java Programming Training while for best practises 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
