Jlist
when user select one item on JList, I can obtain selection by:
String input= jList.getSelectedValue().t
However, I want to get the first item on the Jlist if user doesn't
make any selection. Thanks.

So you want to select the visible item even if they don't click. Is that correct?
When would it change the selection?
Why not use a JComboBox instead?

before i change to combobox, i just wonder whether i can display only 1 item at a time in comboBox?
a combo only display ones at a time, it uses a pull down to change the displayed item
