        j.setName(name);
        j.addActionListener(new R4());
        j.setActionCommand(text);
        j.setVisible(false);
        new Recipe(text);
    }

i don't know how to do this

new addNewButton("CobbleStone", "Block.cobblestone");

panel4.add(CobbleStone);

protected static JComponent addNewButton(String text, String name)
    {
        JButton j = new JButton("test");
        j.setName(name);
        j.addActionListener(new R4());
        j.setActionCommand(text);
        return new JButton(text);
    }

panel4.add(<buttongroup>);

<buttongroup>.setVisible(true);

<buttongruop>.setVisible(false);

define an array that holds the components:  Component[] compAry = {comp1, comp2};
begin loop through the array:  for(int i=0; i<compAry.length; i++) {
get next component from array :    Component aComp = compAry[i];
do whatever with the component:  aComp.someCompMethod();
end loop:                        }
