Need help with compiler error

I get this error: ./ScrabblePlayer.java:19: error: char cannot be dereferenced boolean isHit = tile.indexOf(tile) != -1; ^ Note: JavaTester.java uses unchecked or unsafe operations. Note: Recompile with -Xlint:unchecked for details. 1 error

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 boolean hasTile(char tile) {
    // TODO: Determine if user has the tile passed in
    boolean isHit = tile.indexOf(tile) != -1;
      if (isHit) {
        return true;
        } else return false;
  }

}

I belive you deferenced a wrong variable. The idea was to check if tile is in tiles not in tile. the signature is <String>.indexOf(<char>) change the line throwing the error to the following:

boolean isHit = tiles.indexOf(tile) != -1;
