Sean, thanks. That worked. 

Please correct me, the printIndividual( ) is a method in Individual class. So I 
need to create a class that extends the Individual class so that I could use 
printIndividual( )? In the owner's manual it stated that genotypeToString( ) 
should be overridden instead.

public class Encoder{
   public static void main(String[] args){
      System.out.println(ParsingIndividual.genotypeToString());
   }
}

class ParsingIndividual extends Individual{
   @Override
   public String genotypeToString(float f){
      return Code.encode(f);
   }
}
