Java JList scroll to selected item

Very funny, just one line of code make it fine.


String[] data = {"one", "two", "three", "four", /* AND A LOT MORE */};
JList dataList = new JList(data);
JScrollPane scrollPane = new JScrollPane(dataList);

/* And scroll to selected index */
dataList.ensureIndexIsVisible(dataList.getSelectedIndex());
