  • Still confused about missing symbolNeil May 27, 2012 at 5:41 PM

    Hello, there. I'm a programming student and while I understand the idea of not finding a symbol, I'm still in need of assistance for my following code: public class FileTicketAsText { private static String file; /** * @param args the command line arguments */ public static void Main(String[] args) { // TODO code application logic here Scanner scan = new Scanner(System.in); String name = getName(scan, " Name"); String symbol = getSymbol(scan, " Symbol "); String title = getTitle(scan, "Title"); String summary = getSummary(scan, " Summary "); String question = getQuestion(scan, " Question"); String answer = getAnswer(scan, " Answer"); String nameFile = file + "txt"; FileWriter outputStream = null; String word = null; try { outputStream = new FileWriter(nameFile); BufferedWriter out = new BufferedWriter(outputStream); out.write(word + "/n"); out.close(); } catch (IOException ex){ Logger.getLogger(Main.class.getName().log(Level.SEVERE,null,ex)); } } private static String getName(Scanner scan, String string) { System.out.print(string + "?"); return scan.nextLine(); } private static String getSymbol(Scanner scan, String string) { System.out.print(string + "?"); return scan.nextLine(); } private static String getSummary(Scanner scan, String string) { System.out.print(string + "?"); return scan.nextLine(); } private static String getQuestion(Scanner scan, String string) { System.out.print(string + "?"); return scan.nextLine(); } private static String getAnswer(Scanner scan, String string) { System.out.println(string + "?"); return scan.nextLine(); } private static String getTitle(Scanner scan, String string) { System.out.print(string + "?"); return scan.nextLine(); } } Specifically, the "Logger.getLogger(Main.class.getName().log(Level.SEVERE,null,ex)); " is giving me trouble, because I cannot find the symbol and such my JDK(NetBeans) is giving me all these imports which I don't understand and don't work. All in all, I am in need for some help

  • cannot find symbolLeo September 2, 2012 at 11:32 AM
