In the hangman game file we set String mMisses and String mHits
whats the purpose of putting the mHits/mMisses = "";
can't we use them when declared them in the beginning of the class?

Java Web Development Techdegree Graduate 22,175 PointsIt is needed because later we wil execute the following:
mHits += letter;
if you leave String mHits;
without String mHits = ""
. Your String will be uninialized or null
And because of that you cannot write mHits += letter
.
Does it make sense now ?
