How do I get the answer

Correct the existing hasTile method to return true if the tile is in the tiles field, and false if it isn't. You can solve this a few ways, however, I'd like you to practice returning the result of the expression that uses the index of a char in a String.

I am adding this to the method:

boolean isTile=tiles.indexOf(tile)!=-1; return true;

Can someone help me understand why it's not working?

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) {
   boolean isTile=tiles.indexOf(tile)!=-1;
   return true;

Your expression is true but ur being asked to return the result of the evaluation of the expression which means u need to write: return (write expression here); if it evaluates to true than the tile is exists in the tiles if it’s false then it’s not.
