how I return count ?
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!
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() {
for (char tile: mHand.toCharArray()) {
if(mHand.indexOf(tile) >=0) ;
}
}

public int getTileCount(char tile) {
int count = 0;
for (int i = 0; i < mHand.length(); i++) {
if (mHand.charAt(i) == tile)
count++;
}
return count;
}

Craig Dennis
Treehouse TeacherThat will work, you can use a for-each loop to loop through the hand too
for (char letter : mHand.toCharArray()) {

6,257 Pointsthe only think that I don't understand in regards to this logic is that the char variable tile is not initialized so how can it be compared to a method or even another variable if the tile variable has no value

thanks Craig ..

877 PointsI'm having the same problem and I got confused with all these different answers but what line would I put the, for (char letter : mHand.toCharArray()) {

Steve Fielding
7,287 Pointsyou can try this <code> public int getTileCount(char tile) { int count = 0; for(char letter : mHand.toCharArray()) //Because we want to compare each tile with the actually tile in hand if(letter == tile) count++; </code>

}
return count;
}

2,470 PointsHi, if your getTileCount does your method return a String or an int? If it is an int then you can simply do.
How ever if you are returning a string then:
