Whether dynamic or not, you would use setText either way. Without knowing more of what you want to achieve it's not possible to advise though

Dear Expert,

Spot on. And as he says, that's the method you are going to end up using. The only other thing that occurs to me that you might mean is that text changes on a mouseover. In which case, you could use a MouseInputAdapter. Although you might also need MouseInfo from the awt too.

Thanks for instant comments. I mentioned that I do not want to use Button.setText methode. I mean to say that insted using setText on every button, I want to make it happen in loop using Component of Panel so as to avoide setText method for every individual Button.

Yes, you can use a loop, but again, setText would be used nonetheless. Typically if you have a large number of components where there is a pattern in one of the attributes (in your case, the text) then you can use an array of Component

Component[] jp1 = jPanel1.getComponents();
        for (Component component : jp1){
            component.setEnabled(false);
        }

using above code, I wanted to set component text and label values. I am unable to achieve the same. I am unable to get such setText or setLabel methodes. I am able to get only setName which is of no use for me. If notthing can be done than no matter I have already done it on individual Button basis.

That's not a particularly good way of doing it, but it might be made to work thus

int index = 0;
        Component[] jp1 = jPanel1.getComponents();

        for (Component component : jp1) {
            if (component instanceof JButton) {
                ((JButton) component).setText(String.format("Button %d", ++index));
            }
        }
