Thanks - but, if I try to run the file with the main() I get the following error:
bad source file: ./IQTester.java file does not contain class IQTester Please remove or make sure it appears in the correct subdirectory of the sourcepath. ./IQTester.java:11: error: cannot find symbolThere are two files (IQTester and IQ) and the IQTester contains the main() Methode.
