Courses Plus Student 23,471 Pointscan't figure out what to do here.....
public int getTileCount() { int count = 0; for (char tile : mHand.toCharArray()) { if (mHand.indexOf(tile) >= 0) { count += 1; } } return count; } }
What am I doing wrong??? It's saying that the method is not defined...Looks like it's defined to me...
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 += 1;
}
}
return count;
}
}

Courses Plus Student 11,859 PointsTo clarify, the exercise appears to be asking, not for the number of tiles (letters) in the Scrabble hand, but for the number of letters of a specific type. For example, how many tiles of the letter B does the hand have. In order to answer that question you must provide to the getTileCount() a parameter, say char tile, and then count the number of such tiles in the hand that match it. It's probably saying it's not defined because you need to define it as getTileCount(char tile) and then rewrite the code to count the matches.

Courses Plus Student 23,471 Pointsi did that and got a compiler error... /ScrabblePlayer.java:24: error: variable tile is already defined in method getTileCount(char) for (char tile : mHand.toCharArray()) { ^ 1 error

Courses Plus Student 11,859 PointsChange one or the other to some other variable, otherwise the compiler thinks you are trying to define the same variable twice. Call the parameter you are passing in t instead of tile and rewrite your algorithm. You need to increment the count when the tile in the hand equals the t (tile) you passed in as a parameter, because then you've found another matching tile in your scrabble hand. (Replace the "mHand.indexOf(tile) >= 0" with "t == tile")

Courses Plus Student 23,471 Pointspublic int getTileCount(char tile) { int count = 0; for (char ti : mHand.toCharArray()) { if (tile == ti) { count += 1; } } return count; i'm now getting the following error...
/ScrabblePlayer.java:30: error: reached end of file while parsing } ^ 1 error
what's missing now???

Courses Plus Student 23,471 PointsI think that was the issue. It's now working. Thank you for your help.
