I’m not sure but I think you might want to pull some of that out of the loop like…

double[] evaluateGainRatio(Instances data) throws Exception{
       double[] gainRatios = new double[data.numAttributes()];
       GainRatioAttributeEval gainRatioAttributeEval = new GainRatioAttributeEval();
       gainRatioAttributeEval.buildEvaluator(data);
       for (int i = 0; i < data.numAttributes(); i++) {.     // or i < gainRatios.length
            gainRatios[i] = gainRatioAttributeEval.evaluateAttribute(i);
       }
      return gainRatios;
   }
