FileWriter problem with my toptenScores method!!!
Hey ya'll -- i'm STILLLLLL writing this dumb trivia program. I'm now having a problem with the FileWriter - that writes the final scores BACK to the toptenFile.
I'm hoping all these troubles are just growing pains of my first "big" program (big for me) - BUT I WORKED on this honker all night last night and into this afternoon and I am at my wits end!
I am posting the writing portion below hoping I am just missing something, but if you guys need the whole code let me know -- and below this code I will show the error I am getting as it trys to write to the file.
if (questionsMissed == 3 )
{
if (score > topScoresInt[0])
{
String name = JOptionPane.showInputDialog(null,
"GAME OVER. Your score is " + score + "\n Please enter you initials - no spaces",// Message to display
"You got a High Score!", JOptionPane.INFORMATION_MESSAGE);
try {
BufferedWriter bw=new BufferedWriter(new FileWriter(toptenFile));String[] scorestoFile = new String[10];
scoreToFile[0] = (score + " " + name);
bw.write(scoreToFile[0] + "\n");
for (i=1; i<=9; i++)
{
bw.write(scoreToFile + "\n");
}
bw.close();
System.exit(0);
} catch (IOException ex) {
ex.printStackTrace();
}
HERE IS THE ERROR WHEN IT TRIES TO WRITE TO THE FILE
Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException
