I dont understand what they are asking for in this problem
public class ScrabblePlayer {
private String mHand;
public ScrabblePlayer() {
mHand = "";
}
public String getTileCount () {
String progress = "";
for (char letter : mHand.toCharArray()) {
}
}
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) > -1;
}
}

I think your return statement needs to move after the first of the closing braces. At the moment, it is inside the for loop so it will return out of the method on the first iteration. You want to return the value after the loop has concluded, outside of the loop's braces.
public int getTileCount (char tile) {
int counter = 0;
for (char letter : mHand.toCharArray()) {
if (letter == tile) {
counter++;
}
} // return after this
return counter;
}
Steve.

I think this is what you need, first you are returning an int not a String, and you will need a tile parameter, a counter, and a loop.

985 PointsSo back to that ScrabblePlayer. I found that it's not enough to know if they just have a tile of a specific character. We need to know how many they actually have. Can you please add a method called getTileCount that uses the for each loop you just learned to loop through the characters and increment a counter if it matches? Return the count, please, thanks!
