如何在Java中更改鼠标光标？

在JList上使用MouseMotionListener来检测鼠标何时输入，然后调用

setCursor

HAND_CURSOR

样例代码：

final JList list = new JList(new String[] {"a","b","c"});list.addMouseMotionListener(new MouseMotionListener() {    @Override    public void mouseMoved(MouseEvent e) {        final int x = e.getX();        final int y = e.getY();        // only display a hand if the cursor is over the items        final Rectangle cellBounds = list.getCellBounds(0, list.getModel().getSize() - 1);        if (cellBounds != null && cellBounds.contains(x, y)) { list.setCursor(new Cursor(Cursor.HAND_CURSOR));        } else { list.setCursor(new Cursor(Cursor.DEFAULT_CURSOR));        }    }    @Override    public void mouseDragged(MouseEvent e) {    }});
