task 2 for scrabble game java

can anyone tell me why this does not work for

"Can you also please help me write out the hasTile method? It should return true if the hand has the tile, and false if it doesn't. Thanks!"

public boolean hasTile(char tile) {
      if (mHand.indexOf(tile)) >= 0; {
        return true;
      } else {
       return false;
      }
    }

Your paren should be after the >= 0 not before it, also no semi-colon there.

Hope it helps!

sorry if this is a dumb question but why the change of syntax between this 'if/else' statement in the challenge exercise and the 'if/else' statement for the hangman game. 

 public boolean applyGuess(char letter) {
    boolean isCorrect = mAnswer.indexOf(letter) >= 0; 
    if (isCorrect) {
      mCorrect += letter;
    } else {
      mWrong += letter;
    }
    return isCorrect;

in this instance only the letter is surrounded by parens. also there is a semi colon at the end of the >=0. just wondering since i know java is very specific.

In the example they both follow the same basic rule that I have noticed. When you are opening a block of code using the "{" you do not use a ";". Also I have noticed that whenever you are opening a new block of code using the curly brackets, you almost always use parens. I'm also a beginner but that's what I have noticed, my word isn't law :) Happy Coding

haha yeah I've noticed that. I have a lot of errors that I have to take the time and figure out but with the help of Craig and all of the other treehouse team members, you'll always come out on top. The forum is also very very helpful, for it shows people of all levels of learning coming together and sharing their personal encouraging thoughts and ideas to make this thing work. I love this place and I am happy for other students like you on the team.
