Java 8 New Features

Java 8 introduces functional programming into Java, which is similar to the features available with languages like Scala, Groovy and grails, etc.


This course helps to develop Java Applications using the new features of Java 8. Java 8 introduces functional programming into Java which is similar to the features available with languages like Scala Groovy and grails etc. This course teaches its participants new features like Lambda Expressions, Concurrency Enhancements, Parallel Streams and many others and it is useful to Java developers who are willing to upgrade to Java 8 features.


This course is mainly made for Java developers who want to learn the new features of Java 8. At the end of this training, participants will be able to:

  • Understand new features in Java 8
  • Understand Functional Interfaces and Lambda Expressions
  • Use Lambda Expressions with Collection Streams and Filters
  • Understand Built In functional interfaces in Java 8
  • Use Parallel Streams
  • Use Concurrency Enhancements in Java 8
  • Use File NIO with Lambda Expressions
  • Use the new Date and Time API with Java 8

Total Duration - 2 Days


Participants who are Java Developers with good experience to Java 6 \/ Java 7 features experience are preferred.
