// This program takes as input the question numbers, the questions, the answers,
// and the points. the question number is saved to the questionNumArray, the
// the question is saved to the questionNameArray, the answers are saved to 
// 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 
// questions have been asked, if so the users final score is the output,
// otherwise, the next question is asked and the score is the output. The loop
// will check if the users score is greater then the highscore, if so the 
// output will be the players score to a file, and the the output to the screen
// will be "Congragulations you beat the highscore!" The loop will then check 
// if the user wants to play again, if so the loop repeats. Otherwise the 
// output will be "Thank-you for playing."

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 :)

java.lang.NumberFormatException: For input string: "None"

Doesn't this give you a clue?
You are trying to convert the "None" into a number, probably with Integer.parseInt(...)

Whenever you call this: Integer.parseInt(...) you need to have a try-catch in order to handle the error if it is not a number.

The errors that you get should tell you at what line it occurred.
