Nee, die map is van objecten op doubles, en ik zoek op integer (als object) Michiel Van Bel wrote:

ehm, die is een map van strings en doubles, en ge haalt er een Integer uit?

I already found it, but I thought this was pretty odd at first, so who can tell me what might be going wrong here :

code :

Map<Object,Double> die = classifier.distributionForInstance(instance); double estimate = 0.0; if (die != null) { System.out.println("size " + die.size()); estimate = die.get(new Integer(1)); <-- line 94 } -------------------------------------------------------------------------

output :

size 2 java.lang.NullPointerException at be.svlandeg.pi.classification.JavaMLClassifier.eval(JavaMLClassifier.java:94)

Obviously, "die" is not null...

estimate is een double en in de map zitten Double's, en de waarde uit de map was een null, achter de java-schermen zorgde het veranderen van Double naar double dus voor 'n nullpointer :-) groetjes Sofie Kenny Billiau wrote:
