Need help with the test please

The problem is in the 'hasTile' method. I would appreciate any help.

Kind regards

ScrabblePlayer.java 
public class ScrabblePlayer {
    private String mHand;

    public ScrabblePlayer() {
        mHand = "";
    }

    public String getHand() {
       return mHand;
    }

    public void addTile(char tile) {
        mHand += tile;

    }

    public boolean hasTile(char tile) {

      if(mHand.indexOf(tile) =< 0){
         return true;
      } else {
       return false;
      }
    }
}

Hi Fahad,

You're getting a compiler error because of the wrong order on your logical operator. You have =<

less than or equal would be <=

and greater than or equal would be >=

The indexOf method will return -1 if it's not found and the zero-based index if it is found.

Anything greater than -1 means that it was found.

equivalently you can without changing the operators:

public boolean hasTile(char tile) {

  if(mHand.indexOf(tile) =< 0){
     return false;
  } else {
   return true;
  }
}

=< is going to generate an error.
