2,222 PointsI am confused with this exercise
The question is loop through the hand and see if your tile matches the hand, then increment a counter.
I already have a method for hasTile and I am using it, so why is this not working?
Maybe the question is not clear to me?
public class ScrabblePlayer {
private String mHand;
public ScrabblePlayer() {
mHand = "";
}
public String getHand() {
return mHand;
}
public void addTile(char tile) {
// Adds the tile to the hand of the player
mHand += tile;
}
public boolean hasTile(char tile) {
return mHand.indexOf(tile) >=0;
}
public int getTileCount(char tile) {
int counter = 0;
for(char ch : mHand.toCharArray()) {
if (hasTile(ch)) {
counter++;
}
}
return counter;
}
}

What you are asking it to do right now is if the check and see if the value passed as ch matches matches a char in tile, which is either going to return 8, for true, since there are eight chars in the hand, or 0, if it doesn't.
What you'll want to do is check and see if ch is equal to tile, so something like this for your if statement.
if (ch == tile) {
counter++;
}
Should set you up nicely.
Thanks, let me know if this doesn't help and I'll try to clarify.

Glad I could help.
