I would like to get the parameter with this program without having to force the keyword contained in the EubotDictionary class

Question

As you can see, these are my three classes I use for this program .. I can not find the way to let me return the two parameters in the sentence even if I do not write the keyword that I have in the array .. i would like to find the way i allow me to write input: "From roma to milano" or "to roma da milano" and have reset the parameters as they are in the code I have already developed .. according to you it is possible to achieve this, in addition to what already does the code which I have proposed to you in vision? Thanks for the attention, and for the time spent for me. Good day !

                dictionary.setTesto(stringInput);

Based on your comment:

public class EubotController {

    private String[] parameter = { "bari", "roma", "milano", "pisa", "firenze", "napoli", "como", "torino" };

    public void processInputString(String inputString) {

        String[] input = inputString.split(" ");
        boolean prefixPrinted = false;

        for (String i : input) {
             for (String p : parameter) {
                if (i.equals(p)) {
                    if(!prefixPrinted) {
                        printPrefix(inputString, p);    //call when the first parameter is found
                        prefixPrinted = true;
                    }
                    System.out.println("The parameters are: " + p);
                }
            }
        }
    }

    private void printPrefix(String inputString, String parameterAfterPrefix) {
        String prefix = inputString.substring(0, 
inputString.indexOf(parameterAfterPrefix)).trim();
        System.out.println(prefix);
    }
 }

I renamed getDictionary, so you need to call now controller.processInputString(string) in your main -method.
