I have a java program that creates a window, with a ComboBox in it. This ComboBox is populated by an array that I have also created in the program. My program runs fine in NetBeans 7.2.1, but when I try to run it in the Windows command prompt, I get grief about it. The exact error I am getting when I javac WK2.java is:
This is what I get when I try to run it despite these warnings:
This is the program code itself:
As I stated, this code works fine in NetBeans, but will not run in the command prompt, and I cannot understand what is going on.![:helpsmilie:]()

If someone could help explain to me what stupid mistake I have made here, I would be eternally in their debt!!![:punk:]()

This is the program code itself:
/*Zachariah A Lloyd
* ComboBox/Array*/
package wk2;
import javax.swing.*;
import java.awt.*;
import java.awt.Event.*;
public class WK2 {
String[]stuff = {"Wo
frame();}
public void frame(){
JFrame F = new JFrame("Blizzard Games");
F.setVisible(true);
F.setSize(240,240);
F.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
JPanel P = new JPanel();
P.add(box);
F.add(P);}
public static void main(String[] args) {
new WK2();}}
As I stated, this code works fine in NetBeans, but will not run in the command prompt, and I cannot understand what is going on.
