1,302 PointsI'm struggling with this scrabble code challenge and I need help.
I keep getting this error :
./ScrabblePlayer.java:9: error: bad initializer for for-loop for( letter : tiles.toCharArray()){
public class ScrabblePlayer {
// A String representing all of the tiles that this player has
private String tiles;
public int getCountOfLetter(char letter)
{
int count = 0;
for( letter : tiles.toCharArray()){
if(tiles.indexOf(letter) != -1)
{
count ++ ;
}
}
return count;
}
public ScrabblePlayer() {
tiles = "";
}
public String getTiles() {
return tiles;
}
public void addTile(char tile) {
tiles += tile;
}
public boolean hasTile(char tile) {
return tiles.indexOf(tile) != -1;
}
}
// This code is here for example purposes only
public class Example {
public static void main(String[] args) {
ScrabblePlayer player1 = new ScrabblePlayer();
player1.addTile('d');
player1.addTile('d');
player1.addTile('p');
player1.addTile('e');
player1.addTile('l');
player1.addTile('u');
ScrabblePlayer player2 = new ScrabblePlayer();
player2.addTile('z');
player2.addTile('z');
player2.addTile('y');
player2.addTile('f');
player2.addTile('u');
player2.addTile('z');
int count = 0;
// This would set count to 1 because player1 has 1 'p' tile in her collection of tiles
count = player1.getCountOfLetter('p');
// This would set count to 2 because player1 has 2 'd'' tiles in her collection of tiles
count = player1.getCountOfLetter('d');
// This would set 0, because there isn't an 'a' tile in player1's tiles
count = player1.getCountOfLetter('a');
// This will return 3 because player2 has 3 'z' tiles in his collection of tiles
count = player2.getCountOfLetter('z');
// This will return 1 because player2 has 1 'f' tiles in his collection of tiles
count = player2.getCountOfLetter('f');
}
}

public int getCountOfLetter(char letter) {
int count = 0;
for(char tile : tiles.toCharArray()) { if(letter == tile) { count++; } } return count; }

2,038 PointsI got stuck on this for a while, you are pretty close. Change the if statement, we don't need to use indexOf as the enhanced for loop is doing this job for us.
Add a new variable in the for statement to look in the tiles array as you have done above. Then simplify the if statement to check whether the new variable and the letter are the same. Finally increment the count then return the value.
Let me know how you get on and I'll send the code if you need it ;)
Cheers Craig
