java paintcomponent in constructor
Ik ben bezig met een java app en wil in de constructor de paintcomponent zetten.
Maar ik krijg foutmeldingen:
1. modifier public not allowed here, protected ook gebruikt krijg zelfde foutmelding
2. @override declaration mag er niet staan
3. ; expected
Hoe kan ik dit oplossen?
alvast bedankt
