use one of the following methods:

1) use an string with an index  for your component  names (like label1 , label2, label3) and then use introspection.

2) put your components in an collection (for example an Array) then iterate over collection content and do what ever you want with them

3) use your parent component (form, dialog) getChildren to get collection of components, and then iterate over them

You can use Layouts to have and arrange your components like labels and textfield and so.
if you want indexing on your components, you can dynamicaly generate your components
when loading your application or in handling an event on some of your components, like changing  state of a comboBox, if you dynamicaly change your form  components( add some components or remove them ) or change the arrangement of comopnents, you shoud call the revalidate method on your component( perhaps a JFrame or JPanel ) to apply this changes.

It's easy, just create an array of components:

JBotton[] buttons = new JButton[10];
for( int i = 0 ; i < 10 ; i++ ) {
buttons[i] = new JButton("Button " + i);
}

May i see the code written by you???
