public int getRemainingTries() { return MAX_MISSES - mMisses.length(); }

mMisses represents an object of the String class. I don't remember from back then, but I don't believe you create a method mMisses();

You may be thinking why not do:

public int getRemainingTries() { 
    return MAX_MISSES - mMisses;
}

The thing is, that is essentially saying take MAX_MISSES (which is an integer value) and subtract a string from it, which doesn't make sense.

You want to subtract another integer from MAX_MISSES (in this case the number of times you have already "missed". You can get the number of times you have missed by getting the length of the string mMisses since you increase the size of mMisses by one each time you miss.

The length of a string can be determined with the 'length(); method.... or in this case specifically mMisses.length().

I hope that answers your question.
