Modern Programming with Java 8

    Modern Programming with Java 8 

                       Workshop

      Refactor your legacy applications using Java 8 features 

The Java 8 release has some of the most important feature additions to the Java language and the library. Key features added in Java 8 include lambda functions, stream API and date and time API. The main benefit of Java 8 features is productive programming: getting work done more efficiently and effectively. 

This 1-day in-depth workshop introduces all the important concepts and features important for leveraging Java 8 features for regular work and improve productivity. What is more, this workshop also covers best practices in using Java 8 features. 

A special feature of this workshop: Learn how to refactor your legacy applications by exploiting Java 8 features including lambdas, streams and date/time API.

Participants’ profile:

Developers/leads with working knowledge in Java programming. No prior exposure to Java 8 features required.

Bring Your Own Device

Bring your laptop and make sure that JDK 8 is installed. We will share a lot of source files before the training - you can try out the programs during the session.

Session breakup:

• Introduction to Java 8 and Functional Thinking
• Lambda Expressions and Built-in Functional Interfaces
• Use the built-in interfaces included in the java.util.function package such as Predicate, Consumer, Function, and Supplier
• Develop code that uses primitive versions of functional interfaces
• Develop code that uses binary versions of functional interfaces
• Develop code that uses the UnaryOperator interface

• Collections with Java 8
• Collections Streams and Filters
• Iterate using forEach methods of Streams and List
• Use Stream API with NIO.2
• Filter a collection by using lambda expressions
• Develop code that uses the Optional class

• Describe Stream Interface and Stream Pipeline
• Use method references with Streams
• Develop code to extract data from an object using peek() and map() methods including primitive versions of the map() method
• Search for data by using search methods of the Stream classes including findFirst, findAny, anyMatch, allMatch, noneMatch
• Develop code that uses Stream data methods and calculation methods
• Sort a collection using Stream API
• Save results to a collection using the collect method and group/partition data using the Collectors class
• Use of merge() and flatMap() methods of the Stream API

• Use Java SE 8 Date/Time API
• Create and manage date-based and time-based events including a combination of date and time into a single object using LocalDate, LocalTime, LocalDateTime, Instant, Period, and Duration
• Work with dates and times across timezones and manage changes resulting from daylight savings including Format date and times values
• Define and create and manage date-based and time-based events using Instant, Period, Duration, and TemporalUnit

• Java Concurrency
• Use parallel Fork/Join Framework
• Use parallel Streams including reduction, decomposition, merging processes, pipelines and performance

• Java 8 Best Practices
• Leveraging Java 8 features through functional thinking
• Writing concurrent code with parallel streams
• Using Java 8 date/time API by migrating from legacy Date and Calendar classes
• Design patterns for functional programming
• Refactoring to Java 8 lambdas and streams
