Stuck with this question, it wants me to return true if the tile is in the word and false if it isnt.

Really stuck with this.

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) {
    // TODO: Add the tile to tiles
tiles += tile;
  }

  public boolean hasTile(char tile) {
    // TODO: Determine if user has the tile passed in
    return false;
  }

}

Hi Ryan...

You need to use the String.indexOf(char) method to determine whether the char tile is present in the String tiles .

IF it is true, meaning the tile is present inside String tiles then it will return an integer > 0. IF false meaning the char tile is not present inside String tiles then it will return -1. Thus we can use this principle to test the hasTile method. Please remember the method hasTile returns boolean not int. This is how I do it:

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) {
    // TODO: Add the tile to tiles
tiles += tile;
  }

  public boolean hasTile(char tile) {
    // TODO: Determine if user has the tile passed in
    return (tiles.indexOf(tile)>0);//<-- this will return TRUE if tile is inside tiles and FALSE if vice versa.
  }

}

I hope this can help a little
