I don't know what the question means by "Increment a counter if it matches." I don't know why I need to increment, what a counter is, or what it is matching to.
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 getTileCount() {
for (char tile: hasTile.toCharArray()) {
//increment counter if it matches.
}
return /*count*/;
}
}

We can do this by.
public int getTileCount(char tile) {
int counter = 0; // we initalize our int counter here
for (char letter : mHand.toCharArray()) {
if (tile == letter) { // check to see if the the char we're currently check matches the tile we are looking for
counter++; // increment counter, which is now one
}
}
return counter; // return a int representing how many times the letter that we searched for was found
}
Should do the trick. Let me know if there's anything else I can further clarify.
