Thread: Methods and Exceptions

I'm working on a program that will do a number of things, the exact function being performed is selected by the user in a menu. (They type in the number corresponding to their choice, a switch statement calls a method to perform said function)

I'm having trouble with the code in regards to the error-handling (I think).

import java.io.*;
import java.util.*;
 
class GuildDKP {
 
	public static void menu () throws IOException {
		BufferedReader input = new BufferedReader (new InputStreamReader (System.in));
 
		int menuChoice;
		int menuFlag = 0;
 
		System.out.println("Please enter the number corresponding to your menu selection:");
 
		System.out.println("1.) Create a new character file.");
		System.out.println("2.) Input new DKP/EPGP values.");
		System.out.println("3.) Delete existing files.");
		System.out.println("4.) Decay existing values.");
		System.out.println("5.) Display the current priority list.");
		System.out.println("6.) Backup existing files.");
		System.out.println("7.) Populate files with random values.");
		System.out.println("8.) Clear files of all existing values.");
		System.out.println("9.) Exit.\n");
 
		while(menuFlag != 1) {
 
			menuChoice = Integer.parseInt(input.readLine());
 
			switch(menuChoice) {
				case 1:
					menuFlag++;
 
					break;
				case 2:
					menuFlag++;
 
					break;
				case 3:
					menuFlag++;
 
					break;
				case 4:
					menuFlag++;
 
					break;
				case 5:
					menuFlag++;
 
					break;
				case 6:
					menuFlag++;
 
					break;
				case 7:
					menuFlag++;
 
					break;
				case 8:
					menuFlag++;
 
					break;
				case 9:
					System.exit(0);
					break;
				default:
					System.out.println("Incorrect input.");
					break;
			} // Case
		} // While
	} // Method: Menu
 
	public static void main () throws IOException {
		System.out.println("Welcome to the GuildDKP program!\n");
 
		menu();
 
 
	} // Method: Main
 
} // Class: GuildDKP

The above code returns the following run-time error:

Exception in thread "main" java.lang.NoSuchMethodError: main

EDIT: I just went full retard all over the place. If anyone else happens to make such a stupid blunder, I'll put the obvious solution in for future reference.

public static void main () throws IOException {

Should be:

public static void main (String str []) throws IOException {

If you want user input via a console, use a scanner. The BufferedReader is for reading in the contents of a file.
