Students who attend this course will leave armed with the required skills to develop maintainable code that easily scales into multi-core environments. Geared for developers currently working in Java 6 or 7 who need to migrate their skills or applications to Java 8, this course will teach students everything they need to successfully master and implement the latest features and benefits of Java 8 and become an effective Java 8 developer.

Working within in an engaging, hands-on learning environment, guided by our expert team, attendees will learn:

• What functional programming means and what it brings to the table
• How Lambda expressions and functional interfaces can greatly enhance other aspects of Java
• Explore the new ‘features’ of the Collection API
• To use the new Stream constructs to work with Collections and Collectors
• How to work with default methods and pass methods as arguments
• How to use the new features to support concurrency in multi-code systems
• To work with the new Date/Time API and other new features
• Specific Java 8 features covered include: Functional programming; Anonymous functions; Lambda expressions and default methods; Streams and Collectors; New Date/Time API; StringJoiner and repeating annotations

This course is designed for experienced Java 7 developers who wish to get up and running with Java 8 immediately. Attendees should have a working knowledge of developing Java 7 applications.
