11,497 Pointswhat's NullPointerException error?
I'm making the hangman game myself and I'm following along with the video, but I don't know where my problem is :
this is my code:
public class Game { private String mAnswer; private String mHits; private String mMisses;
public Game(String answer) { answer = mAnswer; mHits = ""; mMisses = "";
};
public boolean applyGuess(char letter) {
boolean isHit = mAnswer.indexOf(letter) >=0 ;
if (isHit) {
mHits += letter;
}else {
mMisses += letter;
};
return isHit;
};
};
and I open up the repl and load the game. and I make the game class, but when I'm using the method applyGuess i get this error:
java.lang.NullPointerException
