Java Java Objects Creating the MVP Counting Scrabble Tiles

Now in your new method, have it return a number representing the count of tiles that match the letter that was passed in

Why is This wrong ???

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

ScrabblePlayer.java
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){
    for(char tile: tiles.toCharArray()){
      if(tile == letter){
        count++;
      }
    return count;
    }





  public boolean hasTile(char tile) {
    return tiles.indexOf(tile) != -1;
  }

}
Example.java
// 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');
  }
}

You need to declare your variable count and initialize it to 0.

Hi there,

You need to declare and initialise the count variable. So before the for loop, add:

int count = 0;

Then, you have got the right idea, but you have put return count; inside the for loop. Move it outside by closing the braces above that line. You just need to add one more } to close out the for loop. Your code will end up looking like this:

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

So, that's basically your code with an additional variable initialisation and some moved braces. Good work!

Hi there ! I'm having a lot of problems understanding this. Why are you using " ==" and what do the shortcout "++" means ? When do they taught that? I find very hard that I see that some people understand this and made up a code right away and I barely can understan what they I asking for.

you might just have to declare count.
