Course Description |
||
Java 8 introduces a number of revolutionary capabilities - many of them
centered on lambda expressions and functional-style programming. These
capabilities add powerful new programming techniques to the language,
but also add complexity. This concise course is focused on introducing
the new capabilities and how to use them. It includes numerous code
examples and programming labs that illustrate all of the new
capabilities. The course is hands on, and requires that students be
comfortable with writing general Java code at an intermediate level,
including the use of interfaces.

Complimentary Skills to have along with Java Programming
- If you are an experienced Java developer, learning a complimentary language to Java should come much more naturally. As an example JetBrains recently created the Kotlin programming language which is officially supported by Google for mobile development. Kotlin compiles to Java bytecode and runs on the JVM; it's purported to address many of Java's shortcomings... |
