Compare String and act

[Chemical]

Γεια σας μια ερώτηση εχω,

έχω φτιάξει 2 text fields kai ενα textarea

θέλω να τοποθετώ 2 λεξεις στα 2 text fields να τα συγκρίνω και να εμφανίζει στο textarea όποια γράμματα δεν είναι κοινά μεταξύ τους.

Σημειώστε ότι μέχρι τωρα το πρόγραμμα μπορεί να κάνει copy ta 2 text fields kai na ta paste sto text area.

Ευχαριστώ.

String s1 = textField1.getText();
String s2 = textField2.getText();
for (int i=0; i<s1.length(); i++){
   String s = s1.charAt(i)+"";
   if (s2.indexOf(s)==-1)
       textArea.append(s);
}
