I'm currently using Eclipse LUNA working on a prompting-guess activity on a Java Basic Course in J2EE. How do I deal with such errors:

“Exception in thread "main" java.lang.NullPointerException at projectHangMan.Prompter.promptForGuess(Prompter.java:13) at projectHangMan.Hangman.main(Hangman.java:10)”

It seems that the error is mainly from this part:

String guessAsString = console.readLine("Enter a letter: ");

Can someone suggest a possible solution to this?
