In my Android app, I enter the string "el". In AsyncTask, I do some operations if I enter exactly "el". In this code :
protected class AsyncTranslator extends AsyncTask<String, JSONObject, String> {
    @Override
    protected String doInBackground(String... params) {
        String mymeaning = null;
        RestAPI api = new RestAPI();
        try {
            //if(params[0] == "el") this doesn't work
            //if(params[0].trim() == "el") this doesn't work either
          //  if(params[0].substring(0, 1).trim() == "e" && params[0].substring(params[0].length() -1).trim() == "l") this doesn't work either
         if(params[0].contains("el")) //this works but it works for other elements containing "el" as well
What kind of if should I write so that it shall work only on string "el". Thanks.
