23 Lambda Ausdrücke JSR-335 Functional Interfaces: An interface with one method Vorschlag zum Sprachumfang von Java SE Early Draft Review 2 Specification vom 19. Juli 2012 file:///c:/java/jsr /index.html Prototype Binaries verfügbar: Lambda Expressions (closures) /* (int x, int y) {return x+y; } */ Parameter Liste -> Operator Expression od.

24 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())); 24 Copyright 2012, Oracle and/or its affiliates.

25 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 25 Copyright 2012, Oracle and/or its affiliates.
