With the final release of Java 8 around the corner, one of the new features I’m excited about is the newDateAPI, a result of the work onJSR 310. While Lambda expressions are certainly the big draw of Java 8, having a better way to work with dates is a decidedly welcome addition. ...
Lambda expressions let you express instances of single-method interfaces (referred to as functional interfaces) more compactly. Default methods are methods in an interface that have an implementation. They enable new functionality to be added to the interfaces of libraries and ensure binary ...
