    jLayeredPane3.add(a);
    a.setBounds(0, y, 1333, 450);
    jPanel1.setPreferredSize(new Dimension(1333, (pos + 480)));
    jLayeredPane3.setPreferredSize(new java.awt.Dimension(1333, (pos + 480)));
    jLayeredPane3.validate();
    jScrollPane1.getViewport().setViewPosition(new Point(0, (pos + 480)));
}

`but how i using different object name` - what do you actually want to do? — Andreas Fester, Jun 14 '13 at 08:13
You mean through the [setName()](http://docs.oracle.com/javase/7/docs/api/java/awt/Component.html#setName%28java.lang.String%29) method? — Andreas Fester, Jun 14 '13 at 08:18
You should definitely use a layout manager like GridBagLayout (http://docs.oracle.com/javase/tutorial/uiswing/layout/gridbag.html) — Stephan, Jun 14 '13 at 09:32

use JPanel.get/putClientProperty,
1. you can to multiply this method
2. every events this/these value, e.g. from Listeners
3. for example

You are using absolute coordinates, a layout manager gives a better GUI across platforms, later Windows versions, accessibility etcetera.

MainConfig.page21.setLayout(new BoxLayout(MainConfig.page21, BoxLayout.Y_AXIS));

Also normally one would not need the JPanel, an event listener would know how to retrieve the panel.

Nevertheless you could maintain an array of JPanels:

List<JPanel> panels = new ArrayList<>();

In addPanel create a local variable, and add that

public void addNewPanel(int y, String title) { // Not static
    JPanel panel = new JPane();
    ...
    panels.add(panel);
}

thank you. it's good idea. but i don't know how many panels adding at runtime. it's unlimited jpanel. – Munkhbat Mygmarsuren Jun 14 '13 at 09:04
Okay I'll change the code. Thought fixed because of i, and for loop. – Joop Eggen Jun 14 '13 at 09:13
Mind, `addNewPanel` is no longer static, as using `panels`. – Joop Eggen Jun 14 '13 at 09:29
i fixed my problem. Thank's all. i like stackoverflow's experts – Munkhbat Mygmarsuren Jun 14 '13 at 10:54
