What does it mean when it says "try returning the result of the expression"

I don't understand what the questions wants. Please help. Take a look at my code if there's any mistakes on my part.

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 hadTile = tiles.indexOf(tile) > 0;
    if (hadTile) {
    return true;
    } else {
      return false;
      }
  }

}

Just return the expression result instead of storing it.

The challenge says, "I'd like you to practice returning the result of the expression that uses the index of a char in a String." So instead of copying the result of your expression into a new boolean variable, and then testing that to determine what to return, just return the result of your expression directly. This will compact your code down to a single line.
