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 = 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.
