Don´t understand how to initialize the for loop the right way. If done like in the video it won´t work, because the char letter is already defined prior in the method. How to tell the machine this "for each tile in tiles..."?
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;
}
private int tileCount = '0';
public int getCountOfLetter(char letter) {
for (char letter : tiles.toCharArray()) {
if (letter.indexOf(tiles)) {
++tileCount;
}
}
return tileCount;
}
}
// 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');
}
}

42,386 PointsHi Arne, just a few minor issues.
public int getCountOfLetter(char letter) {
int tileCount = 0; // move this to here, and make sure that it's an integer (no quotes)
for (char tile : tiles.toCharArray()) { // change the variable to anything but letter, tile sounds good :)
if (tile == letter) { // you can compare two characters for equality with double equals
++tileCount; // would normally be written as tileCount++, but not required to change
}
}
return tileCount;
}
