public String getTileCount(){ String count = ""; for(char letter: mHand.toCharArray()){ char display = '-'; if(mHand.indexOf(letter) >= 0 ){ display = letter; } count += display; } return count; }
public class ScrabblePlayer {

The method needs to take a char
as a parameter and return an int
. A for:each
loop can then be used to iterate through the mHand
string and count how many instances of that char
occur. So, if the player's hand was H E L L O, the method would be called like: getTileCount('L');
and it would return 2, the number of Ls in the hand.
My solution looks like:
public int getTileCount(char tile){
int count = 0;
for (char letter : mHand.toCharArray()) {
if(letter == tile){
count++;
}
}
return count;
}
I hope that makes sense!
Steve.
