Is there any substantial difference beyond the less bulky syntax?
I purchased and skimmed Venkat's draft e-book on functional programming in
Java 8:
http://pragprog.com/book/vsjava8/functional-programming-in-java
My first disappointment is that if you've seen his live presentations on
functional programming -- which are extremely entertaining btw -- the book
doesn't have newer or more in depth content.
But the larger disappointment is that all of these functional practices are
things I'm already used to in older versions of Java as long as you can use
the bulkier anonymous inner class syntax and a third party functional
collections library.
For example, the book shows you how to do standard stuff like:
public static void runLocked(Lock lock, Runnable block);
runLocked(lock, () -> {/*...critical code ... */});
Java 5/6/7 code does this all the time like with the older bulkier syntax:
runLocked(lock, new Runnable() {
@Override public void run() {
/* Critical code */
}
});
