Answer 1

You could download OpenJDK 8 which is scheduled for prodcution release next year and use the new Lambda Expressions for functional programming. See http://macgyverdev.blogspot.se/2012/10/functional-programming-in-java.html for examples of how these closures will be used in the Collection APIs and how they compare with pre-Java 8 solutions like Guava and LambdaJ.
