674 PointsWhen I run the preview it all checks out. However it keeps saying the answer is still wrong. Not sure what I am missing.
It seems to want a char returned but in the question it asks for a number. Am I missing something or just not understanding the question?
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() {
int count = 0;
for (char tile : mHand.toCharArray()) {
if (mHand.indexOf(tile) >= 0) {
count++;
}
}return count;
}
}

28,694 Pointstry:
public int getTileCount(char x) {
int count = 0;
for (char tile : mHand.toCharArray()) {
if (tile== x) {
count++;
}
}
return count;
}
the problem with:
for (char tile : mHand.toCharArray()) {
if (mHand.indexOf(tile) >= 0) {
is that you're counting the occasions a character is in the same string that you got the character from. As a result, it's just going to give you the length of the string.
