88分王的新问题---在程序中用到非class资源的url问题

[alin19]

Toolkit kit = Toolkit.getDefaultToolkit();
welcomeImage = kit.getImage(getClass().getResource("/workbench/pics/welcome.gif"));

一定要这样使用图片，如果不加getClass().getResource（）则打包成*.jar
后它将不使用jar文件内的图片，而去寻找/workbench/pics/welcome.gif

getClass().getResource（）这两个方法到底是怎么回事情呢，及对他们使用的补充
请指教（我懒的看doc)

其实getClass().getResource()在载入资源是ClassLoader在做载入，原理基本和类的载入类似，因此使用的是相对路径。

还有别的解释吗？

getResource

public URL getResource(String name)

Finds a resource with a given name. This method returns null if no resource with this name is found. The rules for searching resources associated with a given class are implemented by the * defining class loader of the class.
This method delegates the call to its class loader, after making these changes to the resource name: if the resource name starts with "/", it is unchanged; otherwise, the package name is prepended to the resource name after converting "." to "/". If this object was loaded by the bootstrap loader, the call is delegated to ClassLoader.getSystemResource.


Parameters:
name - name of the desired resource
Returns:
a java.net.URL object.
Since:
JDK1.1
