JavaMenuBar ?? won't show up
I have a programming assignment where I need to add a JMenuBar at the top with very basic functions
File - Query - Help
I believe all of my code is correct, but no menu bar shows up when I try to:
frame.setJMenuBar(JMB);
I've been looking on the net and the syntax seems to be correct, but like I said...no bar at the top..
Any suggestions?
Code:
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
import java.util.*;
