// This program takes as input the question numbers, the questions, the answers,

// the answersArray and the points are saved to the answersNumArray.
// 
// This prgram will then and check if the user wants the rules, if yes the output 
// will be the rules. The loop will then generate a random question, and take as 
// input a guess from the user, the program will
// check if the guess is equal to one of the answers in answersArray, if so 
// the loop will add the points in answersNumArray to the score, add one to the
// correct answers, and add one to found, the output will be the points won and
// "Correct". the loop will then check if found is equal to 1 if not one is 
// added to strikes and the output is "Incorrect". The loop check if three

This is the highscore file

137

I keep getting this error:
java.lang.NumberFormatException: For input string: "None"
at java.lang.NumberFormatException.forInputString(Unknown Source)
at java.lang.Integer.parseInt(Unknown Source)
at java.lang.Integer.parseInt(Unknown Source)
at FamilyFeud.main(FamilyFeud.java:128)

I cant figure out the solution what so ever
Please and thank you :)

Your error indicates that you attempted to parse an integer at line 128 of your program (which is correct: it says Integer.parseInt(input)). However, the program was unable to parse an int, because your input did not immediately contain an integer. Which means you are reading in the file incorrectly. For example if you say something like Integer.parseInt("This isn't an int!"); it will throw the same exception/error.

hope that helps

Nothing seems to work, anyone out there that can help?
