jdk8-experiments

Personal repository for experimentation with the new JDK 8 features.

ant clean compile dist

I got pretty excited with Java 8, long before they even reached general availability. I tought myself how to build the the JDK and started playing with their new features. I was psyqued about functional programming back then and I just couldn't wait to get may hands on their latest build. In those days there weren't such frequent builds as they do today.

Interesting Stackoverflow Answers

Since I was following the project so close back then, I managed to answer a few very interesting question in Stackoverlow.

• Why There's Interface Pollution in Java 8
• Should I use Java8/Guava Optional for every method that may return null?
• Why are Java 8 lambdas invoked using invokedynamic?
• Remove Elements from a Collection while Iterating
• Lambdas, multiple forEach with casting
• How to specify function types for void (not Void) methods in Java8?
• Adding two Java 8 streams, or an extra element to a stream
• How do I use the new computeIfAbsent function?
• CompletableFuture in loop: How to collect all responses and handle errors
• Is polymorphism possible without inheritance?
• Why is “final” not allowed in Java 8 interface methods?
• Java 8: Mandatory checked exceptions handling in lambda expressions. Why mandatory, not optional?
• Why does Iterable not provide stream() and parallelStream() methods?
• Java Lambdas and Closures
• Why doesn't Java 8's ToIntFunction extend Function<T, Integer>
• Parallelism in Java 8
• Java 8 default method readability
• Java 8 dancing around functions as first class citizens?
• Why does Guava's Optional use abstract classes when Java 8's uses nulls?
• Why an Anonymous class can't implement multiple interfaces directly?

And many more...
