Super newbie - Variables and inheritance?

Question is in the comment:

    public boolean applyGuess(char letter) {
        letter = validateGuess(letter); /*If I invoke applyGuess(m), wouldnt that make this line of code into m = validateGuess(m), which dosent make sense? how does this work? */
        boolean isHit = mAnswer.indexOf(letter) >= 0;
        if (isHit) {
            mHits += letter;
        } else {
            mMisses += letter;
        }
        return isHit;
    }

letter contains a value, but as a variable is able to be changed.

letter = validateGuess(letter);

passes the value to the validateGuess method first, and then assigns whatever is returned from that method into the letter variable. Remember the variable is just a named container for a value.
