How to open a new JFrame through a JMenu Item?

Question

Right, so I already looked at multiple questions regarding something close to this but not what I need help with.

What my issue is, what would I call so that when "New" is clicked, a new Frame would open (the same but just opened again). The system prints out the string, so I know it's working. I just need to figure out how to open a new window.

 mntmNew.addActionListener(new ActionListener() {
            @Override
            public void actionPerformed(ActionEvent arg0) {
                System.out.println("Opening a new window.");

            }
        });

How did you show the first window? You should be able to use the same code if you got it to display once. — takendarkk, Jan 18 '15 at 01:13
It's exactly the same as how you'd open and create **any** JFrame. Surely you can extrapolate from this, no?

YourJFrameClass frame = new YourJFrameClass();
frame.<function to show it>();

then you will maybe make it modal or close the previous one.

How would you make a JFrame modal?? Surely you meant JDialog, right? – Hovercraft Full Of Eels Jan 18 '15 at 01:18

"Function to show it"...like setVisible? – MadProgrammer Jan 18 '15 at 01:36
yes, it can be either a function that you implemented which calling it, or either it's constructor which makes all the GUI building and calling it at the end – roeygol Jan 18 '15 at 01:38
