639 PointsEnhanced For Loop
Hi,
I'm getting an error telling me to use an enhanced for loop when I execute the code below
public int getCountOfLetter(char letter){ int count = 0;
char[] charArray = tiles.toCharArray();
for (char s : charArray) {
if (s == letter) {
count++;
}
}
return count;
}
What am I doing wrong?
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 int getCountOfLetter(char letter){
int count = 0;
char[] charArray = tiles.toCharArray();
for (char s : charArray) {
if (s == letter) {
count++;
}
}
return count;
}
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');
}
}

639 PointsSolved it!
It needed me to put the toCharArray() method
char[] charArray = tiles.toCharArray();
into the for statment
Hope this helps someone else who gets stuck
