Then in each iteration of the loop use an if statement to compare the current character in the array with tile. If they are the same increment count, which you have defined as an int and initialized to zero outside the for each loop. Finally, return count.

23,733 PointsHi Adrian! Here's the complete code, just in case you're still having difficulty with it:
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 int getTileCount(char tile) {
int count = 0;
for (char c: mHand.toCharArray()) {
if (c == tile) {
count++;
}
}
return count;
}
}

2,131 PointsCan you show me an example please? I still can't figure it out.
Kourosh Raeen
23,733 PointsThe for each loop looks like this:
for (char c: mHand.toCharArray()) {
if ( ) {
}
}
See if you can figure out the if statement. Let me know if you need more help.

2,131 Pointspublic String getTileCount() { String count = ""; for (char c: mHand.toCharArray()) { if (mHand.indexOf(tile) >= 0) { } } return count; }
This is what i have.
Kourosh Raeen
23,733 Pointscount should be of type int so that you can increment its value. The if statement should check to see if c is equal to tile. If they are equal then do count++.

2,131 PointsThank you! You were very helpful.

2,131 Points"So 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!"
