我试图使一个JLabel下划线。我到处都找过了，但一无所获。即使在属性中，也没有标记JLabel的选项。我能做什么?
JLabel label = new JLabel("<HTML><U>YOUR TEXT HERE</U></HTML>");
label.setCursor(Cursor.getPredefinedCursor(Cursor.HAND_CURSOR));
或
JLabel label = new JLabel("Underlined Label");
Font font = label.getFont();
Map attributes = font.getAttributes();
attributes.put(TextAttribute.UNDERLINE, TextAttribute.UNDERLINE_ON);
label.setFont(font.deriveFont(attributes));
JLabel label = new JLabel("Underlined Label");
Font font = label.getFont();
Map<TextAttribute, Object> attributes = new HashMap<>(font.getAttributes());
attributes.put(TextAttribute.UNDERLINE, TextAttribute.UNDERLINE_ON);
label.setFont(font.deriveFont(attributes));
