Refactoring to Java 8 (with lambdas and streams) using Eclipse

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. 

In this completely hands-on session (extensive set of sample programs will be shared to all participants), this workshop introduces all the important concepts and features important for leveraging Java 8 features for regular work and improve productivity. Attraction: Demonstration of Eclipse features for automatic refactoring to lambdas. Special feature: Live demo of refactoring open source legacy code base to show how lambdas and streams can result in shorter and effective code.
