Java 8 is a major evolution in the Java programming language and platform. The language has been expanded dramatically to support lambda expressions, functional programming styles, and enhanced performance. The Java libraries have been extended significantly to take advantage of these new language features, and to offer many improvements in areas such as concurrency, security, and JavaScript integration. This course takes a detailed look at all these new features, with extensive examples and hands-on exercises using the latest development tools.
