Open elements and struct of jFrame in another like a menu

i have 5 jFrames in my java project. And i want to make like a Main Menu.
I mean, i want that the program starts with a jFrame and when i click a button insteand of open the jFrame, all the elements like labels, buttons and tables are being shown in my principal jFrame.
And if i click other button the main frame will clean and charge other jframe.
It is possible? im programming with java jdk 8 and netbeans.
Thanks
Edit:
I think who marked duplicate didn't understand my question. I don't want to open or close the frame, or other frames, I want to load the structure and components of several in the same frame. Please read my question before you start complain that is duplicated

Yes this can be solved by getting the contentPane (usually a JPanel) from the JFrame whose content you want to display within the currently displayed JFrame, and making it the contentPane of the displayed JFrame, for example:
// create the new JFrame, the one whose content you wish to display
NewJFrame newJFrame = new NewJFrame();
// get its contentPane
Container newContentPane = newJFrame.getContentPane();
// add this content pane into the displayed JFrame
displayedJFrame.setContentPane(newContentPane);
// revalidate and repaint the JFrame so that its new data is well displayed
displayedJFrame.revalidate();
displayedJFrame.repaint();
// displayedJFrame.pack(); // and you might need to do this if sizes are way off
But this extra gymnastics is bulky, prone to bugs and unnecessary. You are painting yourself in a corner by having your class extend JFrame, forcing you to create and display JFrames, when often more flexibility is called for. In fact, I would venture that most of the Swing GUI code that I've created and that I've seen does not extend JFrame, and in fact it is rare that you'll ever want to do this. More commonly your GUI classes will be geared towards creating JPanels, which can then be placed into JFrames or JDialogs, or JTabbedPanes, or swapped via CardLayouts, wherever needed. This will greatly increase the flexibility of your GUI coding.
For this situation what I recommend is that you do that, that your GUI classes create JPanels, and that you add the ones that you want to swap to a JPanel that uses a CardLayout. And then whenever you want to show a different "card", call show(...) on the CardLayout object, passing in the JPanel that uses it, as well as the String key that was used when adding the "card" JPanel to the CardLayout-using JPanel. This is all well-explained in the CardLayout Tutorials.

Is it possible to switch from screen to screen by just using one JFrame?

Is it possible to switch from screen to screen by just using one JFrame?
Do i need to create another JFrame or use JPanels and turn it on/off on button presses to create an illusion of jumping from screen to screen?
Or is there any other more efficient way to do this with other containers like
JDesktopPane, JLayeredPane, JInternalFrame and etc in netbeans ide?
What is the purpose and difference in usage of Swing Containers & Swing Windows?
When to use Containers and when to use windows?
By the way, i'm trying to build an Inventory System App Interface.

you can use JInternalFrame which is make how many child Frames you want in a JFrame and you can do also iconified,closable,resizable ... by make them true in child Frames until you can use JPanel instead of JFrame and switch between them(child Frame's) by just one click!
Edited------------
For Example:
JInternalFrame jInternalFrame = new JInternalFrame("Hello!",true,true,true,false);
jInternalFrame.setSize(160,200);
getContentPane().add(jInternalFrame);
jInternalFrame.add(panel);
jInternalFrame.setVisible(true);

And when you click the back button, it will return to the initial menu without popping out a dialog or changing the size or location of the window.
Sound like you can use a CardLayout. Read the section from the Swing tutorial on How to Use Card Layout for more information and examples.

external panels in swing

I have something like this...
Its a bunch of JLabels within JPanels inside a
--JFrame
--JPanel
--Set<JPanel>
--JLabel object contained in each JPanel object cotained in the set
I want to create an external panel/frame so that each time I hover over each individual JPanel, a new frame/panel pops up giving me some data. This will essentially overlap over the JFrame.
Its pretty brief but I just need some guidance as to what I need to look up.

Maybe you can just use JToolTip. When the mouse hovers over the label for a couple of seconds it will display automatically. See the section from the Swing tutorial on How to Use Tool Tips.
Or if you want something more complicated use a MouseListener. On mouseEntered() you can display a JPopupMenu or an undecorated JDialog.
You can start by reading the Swing tutorial on How to Write a Mouse Listener.

Swing: Click on a button in a frame, show another frame with different components

I am developing an application which needs to pop up new JFrame B with different components, when I click on a button on JFrame A. How do I achieve that?
I don't want to use the tabs.

Use a JDialog , problem solved!
See this java tutorial for more help : How to Make Dialogs

I'm not sure why no one has suggested CardLayout yet, but this is likely your best solution. The Swing tutorials have a good section on this: How to use CardLayout

In a nutshell (a simple solution), you register a listener with the JButton and then have the listener perform the tasks you want it to perform:
setVisible(true) for one frame.
setVisible(false) for the other one.
Regards!

One way to approach this would be to create another jFrame and then add a listener onto your button like so:
jFrameNew.setVisible(true);
This way you have a whole new frame to work with. If you want to just have a pop-up message you can also try using the jDialog frames.
Depending on which IDE you are using...for example Netbeans has a gui that makes designing interfaces slightly easier, so you can test out the different frames.

swing: JPanel vs. modal/modeless dialog?

I want to implement some functionality in a library and make it available as a GUI building block for my applications. I think I would like to implement it as something that extends a JPanel, so it can be embedded as a component in other windows.
Is there a reason I should use a JDialog instead? How easy is it to create a JDialog which displays a JPanel along with minimal other appropriate components? (e.g. just a border/closebox/etc for modeless dialog; for modal, the same + an OK/Cancel)

You should extend JDialog only if you want a Dialog, and if you want just a Panel that you can use in other Windows or Frames you should extend JPanel.
Yes, it is easy to create an JDialog just containing a JPanel with a border, closebox and OK/Cancel, both modal and not modal.
Have a look at How to Make Dialogs and How to Use Panels

I would make it a JPanel. That way you could reuse it in other components or drop it into a JFrame (by calling setContentPane) if you want to run it as a standalone. The only reason for you to need a JDialog is if you want to make your component modal.
