Could not compile (generics are not supported)

I've got 3 platforms in Platform Manager:

JDK 1.6.0 (default)

Hotspot 1.5.x

Hotspot 1.4.x

i tried to compile a "ProgressBarSample.java" of the online-tutorial, but the studio returns me error in line:

class Task extends SwingWorker<Void, Void> {

@Override

and on the out says:

generics are not supported in -source 1.4

(use -source 5 or higher to enable generics)

class Task extends SwingWorker<Void, Void> {

annotations are not supported in -source 1.4

(use -source 5 or higher to enable annotations)

@Override

how could i enable -source 5? i use everywhere the 1.6.0 SDK as default.
