JLabel中如何假如图片

请问JLable中除了下列方法假如图片，还有没有其他的途径
或者说是JLable中有没有的内部方法直接调用。
ImageIcon go_offimage=new ImageIcon("Images/go_off.gif");
JLable lable=new JLable(go_offimage);

JLabel label = new JLabel (new ImageIcon ("Images/go_off.gif"));

setIcon

public void setIcon(Icon icon)

Defines the icon this component will display. If the value of icon is null, nothing is displayed.

The default value of this property is null.

This is a JavaBeans bound property.
