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

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

OpenJFX Project
• OpenJFX is the open source home of JavaFX development
• Goal of OpenJFX is to build the next-generation Java client toolkit
• Project OpenJFX intends to file a JSR in the Java SE 9 timeframe and be part of the JDK
• In 2011 the JavaFX toolkit was completely rewritten in Java and released by Oracle as JavaFX 2.0
• Oracle announced that it would donate the JavaFX toolkit to the open source community and by
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
