I get this error when I run my code, I can't understand what it means:
./ScrabblePlayer.java:23: error: bad initializer for for-loop
for (tile : count) {
^
My code:
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) > -1;
}
public String getTileCount() {
int count = 0;
for (tile : count) {
count += 1;
}
return count;
}
}

8,243 PointsAh, okay. What code could I add to reference 'tile' in my 'for' loop? I tried many things, and it didn't work.

29,567 PointsThe assignment probably has you doing it this way:
public int getTileCount(char tile){
int count = 0;
for(char letter : mHand.toCharArray()){
if(tile == letter)
count++;
}
return count;
}

29,567 PointsYes that's right my bad.

29,567 PointsI changed it, thank you.

29,567 Pointspublic int getTileCount(char tile) {
int count = 0;
for(int i = 0; i < mHand.length(); i++){
if(mHand.charAt(i) == tile)
count++;
}
return count;
}
I haven't ran it but that should work.

29,567 PointsPaste your entire code, and I'll look at it.

8,243 PointsNevermind, fixed it. Thanks for the help!

29,567 PointsNo problem :)

29,567 PointsYou need to add a type before your "tile".
It will loop through your mHand, taking each character and storing it in your char tile variable. Make sure that you add code that will reference the "tile" variable in your for loop code block.
