Hi Eric, thanks for your help.
No error messages in the import list at the top of the class. The list is:
import java.math.BigInteger;
import java.util.ArrayList;
import java.util.Enumeration;
import java.util.Hashtable;
import java.util.Random;
import org.apache.commons.math.distribution.ChiSquaredDistribution;
import org.apache.commons.math.distribution.ChiSquaredDistributionI mpl;
Is there an import statement missing?
I get a list of possible quick fixes when I hover the mouse over the
code - screenshot attached showing the options. Doesn't mean much to me,
I'm afraid. Does it make sense to you?
