Help w Scrabble challenge, getTileCount() method...

Stuck at this error, don't know why mHand.hasTile(tile) isn't working as expected - a small clue would be appreciated, thx. (Also not sure why code I paste into this form is being reformetted - trying comments to see if it will ignore.)

/* ERROR:

ScrabblePlayer.java:25: error: cannot find symbol if (mHand.hasTile(tile)) { ^ symbol: method hasTile(char) location: variable mHand of type String 1 error

CODE:

public class ScrabblePlayer {
    private String mHand;

    public ScrabblePlayer() {
        mHand = "";
    }

    public boolean hasTile(char tile) {
        return mHand.indexOf(tile) > -1;
    }

  // return number of matched characters
    public int getTileCount() {
        int count = 0;
        for (char tile: mHand.toCharArray()) {
            if (mHand.hasTile(tile)) {      
                count++;
            }
        }
        return count;
    }
}

If you use three back ticks ` followed by java it will color code correctly. Make sure to mark Kristian's answer as best answer, if it worked for you! They deserve points!

Because mHand is a string and therefore does not have the method hasTile in this code:

int count = 0; for (char tile: mHand.toCharArray()) { if (mHand.hasTile(tile))

If this is used in a method in the class ScrabblePlayer just do: if(hasTile(tile))

Many thx KG, makes sense - that let it compile without error.
