New to Java

Hi,

I've several panels and and several components (TextField, TextLabel, Table, etc) on each panel. I want to get a specific component from a panel change the text of this component in each loop. So How can i get the component with its name. I can get the component with number but i don't like this method since adding or removing components from panel changes the number.

JTextField tf = (JTextField)mySOM.ControlsPanel_1.getComponent(6);
			tf.setText(String.valueOf(nbhRadius));
