Java Java Objects Creating the MVP Scrabble Tiles

I am stumped and I don't know how to ask for help here!

public boolean hasTile(char tile) { // TODO: Determine if user has the tile passed in boolean gotTile = tiles.indexOf(tile) != -1; if (gotTile) { tiles += tile; } else { gotTile = false; } return gotTile; } // this obviously is wrong. Help!

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
    boolean gotTile = tiles.indexOf(tile) != -1;
    if (gotTile) {
        tiles += tile;
    } else {
        gotTile = false;
    }
    return gotTile;
  }

}

Hi Brad

The challenge only asks you to return True if tile indeed inside tiles and False if tile is not in the tiles String. You don't have to add tile into the tiles. You can just do this like this:

public boolean hasTile(char tile) {
    // TODO: Determine if user has the tile passed in
    return (tiles.indexOf(tile)!=-1);

the method already stated it will return a boolean. And the (tiles.indexOf(tile)!=-1) part will return boolean (True or False) thus you can just put it in the return section of the method's code.

I hope this can help a little
