Question

 /**
     * @return Returns the parameters.
     */
    public Set<FeatureParameterDTO> getParameters() {
        return this.parameters;
    }

how can i get value from getParameters? toString is not ok? What is correct way?

You possibly have multiple values. So you’d have to iterate over them. You should be more precise with your questions. This one is quite vage. Just a quick example:

import java.util.Set;
import java.util.TreeSet;


public class SetTest {

Set<Integer> parameters = new TreeSet<Integer>();

  public static void main(String[] args) {
      SetTest st = new SetTest();
      Set<Integer> param = st.getParameters();
      param.add(1);
      param.add(2);
      param.add(3);

      for (Integer myVal : param) {
        System.out.println(myVal);
      }
   }

   public Set<Integer> getParameters() {
      return this.parameters;
   }
}
