JButton as variable loaded into a ArrayList??

Question

Hi!
I'm trying to load an ArrayList with jbuttons .... when explicitly added like this , it works fine......
package AddRFSwitchPac;
import java.awt.Color;
import java.util.ArrayList;
import javax.swing.JButton;
* @author Richard
public class ButtonArrayList {
     * Creates a new instance of ButtonArrayList
    public ButtonArrayList() {
        ArrayList<JButton> buttons = new ArrayList<JButton>();
        buttons.add(AddRFSwitchMain.jButton1);
        buttons.add(AddRFSwitchMain.jButton2);
        buttons.add(AddRFSwitchMain.jButton3);
        buttons.add(AddRFSwitchMain.jButton4);
        buttons.add(AddRFSwitchMain.jButton5);
        JButton button = (JButton)buttons.get(3);
        if (button != null)
        button.setBackground(new Color(0,0,0));
}.... but when I try to load the jButtons from a loop .... It will not work ...
package AddRFSwitchPac;
import java.awt.Color;
import java.util.ArrayList;
import javax.swing.JButton;
* @author Richard
public class ButtonArrayListLoad {
     * Creates a new instance of ButtonArrayListLoad
    public ButtonArrayListLoad() {
            int rc = AddRFSwitchMain.jTable1.getRowCount();//jTable is 5 rows ... this equates to 5 jButtons
            ArrayList<JButton> buttons = new ArrayList<JButton>();
       for(int i = 0; i <= rc; i++) {
            String key = String.valueOf(i);
            JButton button = new JButton();
           // buttons.add("key");// this doesnt work as string "key" or an int (i)
            // here I pick what button I want out of the Arraylist
            JButton button = buttons.get(2);
       if (button != null)
            button.setBackground(new Color(0,0,0));
}

OOOOOOOPS ! .... I was not running a valid test here !! ( was working on one revision ...but running another)
This is the code I need to work ...
package AddRFSwitchPac;
import java.awt.Color;
import java.util.ArrayList;
import javax.swing.JButton;
* @author Richard
public class ButtonArrayListLoad {
     * Creates a new instance of ButtonArrayListLoad
    public ButtonArrayListLoad() {
            int rc = AddRFSwitchMain.jTable1.getRowCount();//jTable is 5 rows ... this equates to 5 jButtons
            ArrayList<JButton> buttons = new ArrayList<JButton>();
       for(int i = 0; i <= rc; i++) {
            JButton button = new JButton();
            buttons.add(button);
            // here I pick what button I want out of the Arraylist
            JButton button = buttons.get(1);
       if (button != null)
            button.setBackground(new Color(0,0,0));
}This code paints nothing to any button.
the buttons I am changing colors for are "AddRFSwitchMain.jButtons 1 thru 4" (located in my form builder GUI)
