636 Pointshave it return a number representing the count of tiles that match the letter that was passed in to the method.
public int GetCountOfLetter (char tile) { int count = 0; for (char tile: tiles.toCharArray()){ if(tiles == letter) { count++; } } return count; } }
public class ScrabblePlayer {
// A String representing all of the tiles that this player has
private String tiles;
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;
}
public int getCountOfLetter(char tile) {
return 0;
}
public int GetCountOfLetter (char tile) {
int count = 0;
for (char tile: tiles.toCharArray()){
if(tiles == letter) {
count++;
}
}
return count;
}
}
// 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');
}
}

4,254 PointsLooks like your issue may be with this block
public int GetCountOfLetter (char tile) { // this variable name should be "letter"
int count = 0;
for (char tile : tiles.toCharArray()) {
if (tiles == letter) {
count++;
}
}
return count;
}
Your first line of that block creates a new variable named "tile" based on the input.
Then when you run your for loop, you create another variable named tile that conflicts with the existing variable.
You then try to compare "tile" and the nonexistent "letter" variable.
This is how it should look
public int GetCountOfLetter (char letter) {
