Boolean method

I am having a hard time understanding how to construct this Boolean method. Can someone help me?

ScrabblePlayer.java
public class ScrabblePlayer {
    private String mHand;

    public ScrabblePlayer() {
        mHand = "";
    }

    public String getHand() {
       return mHand;
    }

    public void addTile(char tile) {
        // Adds the tile to the hand of the player
    mHand += tile;
    }

    public boolean hasTile(char tile) {
      if (mHand.hasTile ()) {
       return true;
      }
      else {

       return false;
      }

    }
}

Within your hasTile method, you are calling the same method again. Instead, try this:

public boolean hasTile(char title) {
   boolean result = false;  // assume the result is false
   if (mHand.indexOf(tile) > 0) {  // this looks for that tile within mHand
      result = true;  // change the result to true
   }
   return result;  // returns the result true or false
}

You're trying to call the method in it's own declaration. You can make it quite simple with if:

if (mHand.indexOf(tile) >= 0) { 
//checks if the char tile is contained in the String. if the value is above -1 then it is and returns true
return true;
} else {  // otherwise it returns false
return false; 
}
