Using the index of a char in a String

I keep getting this syntax error and I have no idea how to index. ./ScrabblePlayer.java:20: error: incompatible types: int cannot be converted to boolean boolean isTile = tiles.indexOf(tile);

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 isTile = tiles.indexOf(tile); 
      if (hasTile){
    return false;
      }

    else return true;
  }

}

Hi Talal, the indexOf method returns an integer, not a boolean.

You can modify it to return directly if you want, or use a variable, such as x in this case.

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