automated buttons implementation in java

I want to have a for loop, that can implement and add a specified number of JButtons the one after the other. I was trying to implement it and this is my code so far:

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;

public class ArrayForm extends JFrame implements ActionListener 
{
    JPanel numPanel = new JPanel();
    JPanel opPanel = new JPanel();

    JTextField textField = new JTextField(25);

    JButton [] buttons = new JButton[10];
    JButton [] OPbuttons = new JButton[6];

    String num="";

    String [] operation = {"+","-","*","/","=","C"};

    public static void main(String[] args) 
    {ArrayForm fobject = new ArrayForm();}

    public ArrayForm()
    {
            setLayout(new FlowLayout());
            setSize(400,300);
            setTitle("Calculator");
            setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
            setLocationRelativeTo(null);

            numPanel.setPreferredSize(new Dimension(180,150));
            numPanel.setLayout(new FlowLayout());

            opPanel.setPreferredSize(new Dimension(200,70));
            opPanel.setLayout(new FlowLayout());

            for (int i = 0; i<10; i++)
            { 
                //The code in here
            }

            for (int i = 0; i<6; i++)
            {
                //The code in here
            }

            add(textField);
            this.textField.setEditable(false);
            add(numPanel);
            add(opPanel);
            setVisible(true);
    }

    @Override
    public void actionPerformed(ActionEvent e) 
    {

    }
}

Can you please help me with for loop part? where the first one is buttons array, and the second one is for OPbuttons array.

Your for loop part might be as follows:

            for (int i = 0; i<10; i++)
            { 
                buttons[i] = new JButton(""+i);
                numPanel.add(buttons[i]);
                buttons[i].addActionListener(this);
            }

            for (int i = 0; i<6; i++)
            {
                OPbuttons[i] = new JButton(operation[i]);
                opPanel.add(OPbuttons[i]);
                OPbuttons[i].addActionListener(this);
            }

What i have understood, is that you are trying to add the buttons of a calculator automatically, within two different panels...

NB: don't forget to add the code for your Action Listener.
