Java 101: The essential Java language features tour, Part 5

This article completes my introduction to new Java language features introduced in Project Coin, the JDK 7 language update.

This month I demonstrate enhancements found in the remaining four features, namely binary literals, underscores in numeric literals, type inference changes, and simplified varargs method invocation.

Where appropriate I’ll also discuss performance and other improvements over prior implementations.
