java 怎么给 Jlabel 添加边框

如果只添加右边框和下边框，不要四周都有，怎么添加？

Answer 1

public class LabelUI extends BasicLabelUI{

@Override
public void paint(Graphics g, JComponent c) {
// TODO Auto-generated method stub
g.setColor(Color.BLACK);
int y = (int) c.getSize().getHeight();
int x = (int) c.getSize().getWidth();
System.out.println(x+" "+y);
g.drawLine(0, y-1, x-1, y-1);
g.drawLine(x-1, 0, x-1, y-1);
super.paint(g, c);
}
}
