2,366 Pointsi dont know what to do here
i dont know how to use the for loop in order to loop
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 letter) {
return 0;
}
}
// 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');
}
}

20,406 PointsIt would be a good idea to read up on enhanced for loops before attempting this challenge.
https://docs.oracle.com/javase/tutorial/java/nutsandbolts/for.html
an enhance for loop takes two main parameters: the name of a variable, and the datatype in which to iterate over. For each iteration over the array, we want to check if the tile in the array matches the char letter we passed in. If so, we want to increment our count by one. After the enhanced for has finished iterating over every tile, we want it to return the number (in this case, the variable count) of matches.
Be sure to also initialize the int count variable to zero.
// A String representing all of the tiles that this player has
private String tiles;
public int count = 0;
public int getCountOfLetter(char letter) {
for (char tile : tiles.toCharArray()) {
if (tile == letter) {
count++;
}
}
return count;
}
