Course Description
Overview
This Migrating to Java 8 course is designed to provide students with knowledge of new language features in Java 7 and Java 8 -- and more importantly illustrates best programming practices as they've been affected by these new features. This is an accelerated course that assumes long experience with earlier versions of Java. Students will leave familiar with various new bits of syntax, and also with an understanding of the exciting new options they have for API design and general-purpose Java 8 coding.Objectives
Upon completion of the Migrating to Java 8 course, students will be able to:
- Take advantage of Java-7 features including strings in switch/case and auto-selection of type parameters for generics.
- Use 'try-with-resources' for simpler cleanup.
- Use Java as a functional language, making appropriate choices of tools including inner classes, functional interfaces, method references, and lambda expressions.
- Use the Stream API for efficient processing of data sets.
