Question

I am getting DB values with following code:

public List<String> getPlayerNames() {
        List<String> playerNames = new ArrayList<String>();
        c = myDataBase.rawQuery("SELECT * FROM PLAYERS",null);
        while (c.moveToNext()) {

            String q = c.getString(1);
            playerNames.add(q);

        }
        c.close();
        myDataBase.close();
        return playerNames;

    }

I now want to compare the items in this List to a String value with following method:

private boolean checkIfExists(String newPlayer) {
        // TODO Auto-generated method stub

        List<String> playerNames = myDbHelper.getPlayerNames();
        //here a loop?! 

        return false;
    }

But I don’t really know how to compare these list items with a string value. I tried with a for loop, but then again, a list doesn’t support a .length() method to go trough all elements? Tnx!

Answer 1

for(String playerName : playerNames){
  if(playerName.equals(newPlayer)){
    return true;
  }
}
return false;
