12,145 PointsI'm stuck, not sure what I'm doing wrong?
I'm not sure if I should use tile of mHand in the for loop?
public class ScrabblePlayer {
private String mHand;
public int getTileCount(){
int counter = 0;
for(char letter:mHand){
if (mHand.indexOf(letter) >= 0){
counter += 1;
}
return counter;
}
}
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) > -1;
}
}

29,567 PointsYou need to start by creating a method header that passes in a char argument and returns the count (int) and name it getTileCount so we have:
public int getTileCount(char tile){
}
Next we have to iterate through the characters of the String mHand and increment the count variable that you are to create, like this:
for(char letter : mHand.toCharArray()){
if(letter == tile)
count++;
}
After your for loop body just return the count.

29,567 Points...and don't forget to add a count variable before your for loop and increment the count during the loop.
