Usage

From source file:FocusTraversalExample.java

    if (!(aComponent instanceof JButton)) {
        return null;
    }/*  w  ww.j  a v a  2s . c o m*/

    // Find all buttons after the current one.
    String nextName = ((JButton) aComponent).getText() + "\0";
    SortedMap nextButtons = buttons.tailMap(nextName);
    if (nextButtons.isEmpty()) { // Wrapped back to beginning
        if (!buttons.isEmpty()) {
            return (Component) buttons.get(buttons.firstKey());
        }
        return null; // Degenerate case of no buttons.
