Lambda Ausdrücke JSR-335
• Functional Interfaces: “An interface with one method”
• Vorschlag zum Sprachumfang von Java SE 8
− 0.5.1 Early Draft Review 2 Specification vom 19. Juli 2012
file:///C:/Java/jsr335-0.5.1/index.html
− Prototype Binaries verfügbar: http://jdk8.java.net/lambda/
•Lambda Expressions (closures)
/* (int x, int y) {return x+y; } */
•Parameter Liste → -> Operator → Expression od. Statements
(String x) -> {return !x.isEmpty();}
•Was hergeleitet werden kann, kann auch weggelassen werden
x -> !x.isEmpty()
reserved.

Lambda Ausdrücke
State of the Lambda 4th Edition

Today we write:
Collections.sort(people, new Comparator<Person>() {
public int compare(Person x, Person y) {
return x.getLastName().compareTo(y.getLastName());
}
});

/* This is a very verbose way to write "sort people by last name"! */

With lambda expressions, we can make this expression more concise:
Collections.sort(people,
(Person x, Person y) -> x.getLastName().compareTo(y.getLastName()));

reserved.

Lambda Ausdrücke – Parallelisiert
State of the Lambda Libraries Edition
List<Student> students = new ArrayList<>(...);
...
double highestScore =
students.parallel()
.filter(s -> s.getGradYear() == 2011)
.map(s -> s.getScore())
.reduce(0.0, Integer::max);

− More readable
− Better abstraction
− No reliance on mutable state
− Runs in parallel
− Works on any data structure that knows how to subdivide itself

Concurrent Bulk Data Operations in Java collections API’s (JEP 107)
− filter/map/reduce

November 2011 the OpenJDK Community had agreed to take it on
• Project OpenJFX is currently focused on absorbing the existing code base from Oracle and building
a functioning community around it
• Oracle's code will be donated in phases with the initial piece being the UI Controls classes
