Dodawanie kilkudziesieciu jpaneli

Witam,
tablice nie są mają mocną stroną, a chciałbym nauczyć się dodawać automatycznie kilkudziesięciu paneli, żeby nie musieć wpisywać ręcznie, bo wiem, że to strata czasu i kiedy tak robię, to aż źle się z tym czuję :D

Otóż stworzyłem coś takiego:

import java.awt.Color;
import java.awt.GridLayout;
import java.awt.BorderLayout;

Niepotrzebny kod usunąłem, zostawiłem tylko to co najgorsze. W taki sposób nigdy nie dodam planszy JPaneli 50x50, bo kod stałby się nieczytelny i za długi. Samą plansze 4x4 w taki sposób pisałem dosyć długo. Jak widać jest tu bardzo dużo powtarzających się etapów. Chciałbym, żeby ktoś pomógł mi w jakiś sposób "zautomatyzować" dodawanie paneli.
Pozdrawiam

Omg,

JPanel[][] panele = new JPanel[50][50];
for(int row=0;row<50;row++)
{
    for(int col=0;col<50;col++)
    {
        JPanel p = new JPanel();
        p.setBackground(Color.WHITE); 
        p.setBorder(BorderFactory.createLineBorder(Color.BLACK));
        p.addMouseListener(new MouseAdapter()
        {
             public void mouseClicked(MouseEvent me)
             {
                  JPanel p = (JPanel)(me.getSource()); 
                  p.setBackground(Color.RED);
                  p.repaint();
             }
        });
        panele[row][col] = p;
        panelglowny.add(p);
    }
}

Korzystasz jeszcze ze stałych i...., proponuję by były one polami w klasie. Nie warto też tworzyć 2500 identycznych listenerów

class Listener extends MouseAdapter
{
    public void mouseClicked(MouseEvent me)
    {
        MojPanel p = (MojPanel)(me.getSource()); 
        p.setBackground(Color.RED);
        p.repaint();
        p.i = 0;    
    }
}
class MojPanel extends JPanel
{
    int i = 1;
    public MojPanel()
    {
        setBackground(Color.WHITE);
        setBorder(BorderFactory.createLineBorder(Color.BLACK)); 
    }
}
...
MojPanel[][] panele = new MojPanel[50][50];
MouseListener listener = new Listener();
for(int row=0;row<50;row++)
{
    for(int col=0;col<50;col++)
    {
        MojPanel p = new MojPanel();
        p.addMouseListener(listener);
        panele[row][col] = p;
        panelglowny.add(p);
    }
}
