Swing application Framework Application lifecycle handling; - launch() - startup() - exit() - shutdown() Action. Performed -> @Action public void open. File() { …} Support for handling resources (formatted strings, images, colors, i 18 n) Support for session states Remove the ’italian-style-code’ which is needed in Swing applications (e. g. listener pattern) © 2004 Capgemini - All rights reserved 2008, July – Andreas Enbohm

Annotation on Types public int do. Stuff(@not. Null String name) { //No need to throw Illegal. Argument. Exception! return name. length(); } public void do. Stuff 2(@not. Negative int age) { this. age = age; } © 2004 Capgemini - All rights reserved 2008, July – Andreas Enbohm

Java SE 7 Language Proposals - Closures (N/A ? ) - ARM blocks - Language level XML support - Java. Beans Properties (like Scala/C#, no need for get/set) Misc. Language Changes - Big. Decimal operator support (+-*/) - String in switch statements - improved catch-blocks (catch (Acces. Ex | Illegal. State. Ex)) - chained method invocations (foo. bar(). baz(), bar(), baz() voids) © 2004 Capgemini - All rights reserved 2008, July – Andreas Enbohm

Closures System. out. print(“Prepare the lobster"); put. In. Pot("water"); System. out. print(“Prepare the chicken"); put. In. Fry. Pan("coconut"); function cook( i 1, i 2, f ) { System. out. print(“Prepare the " + i 1); f(i 2); } cook( "lobster", "water", put. In. Pot ); cook( "chicken", "coconut", put. In. Fry. Pan ); © 2004 Capgemini - All rights reserved 2008, July – Andreas Enbohm

Java SE 7 JVM - invokedynamic (good for scriptlanguages builders) - tired compilation (improve JIT, do at startup) - G 1 Garbage Collector (’collect where it is most needed’) - More script engines - Cheap concurrency -> Scala/Erlang Actors (continuation closure) © 2004 Capgemini - All rights reserved 2008, July – Andreas Enbohm
