示例1: getProperty
import java.awt.Image; //导入方法依赖的package包/类
/**
* Return a property of the image by name. Individual property names
* are defined by the various image formats. If a property is not
* defined for a particular image, then this method will return the
* UndefinedProperty object. If the properties for this image are
* not yet known, then this method will return null and the ImageObserver
* object will be notified later. The property name "comment" should
* be used to store an optional comment which can be presented to
* the user as a description of the image, its source, or its author.
