Variable intialization

In this video Craige initialize variables inside the Constructor: like this.answer = answer; and at the same time he initialized hits = ""; and misses = ""; My question is why he didn't initialize this.hits = hits; and this.misses = misses;

When you initialize an object there can be parts set by the client or user of the object, and parts that don't need to be because they always start with the same values. answer is something the client sets because it will vary from game to game, hence why it's passed in through the constructor. hits and misses are different. Since the game is just starting and there have been no guesses yet they will always be empty strings. There is no point in passing them through the constructor, and requiring them to be is needlessly complicated for the client/user of the class.
