写一个方法，向它传递一个对象，循环打印出对象层次结构中的所有类?thinking in java里面的一个习题不知道如何做请教高手？
&&&&来源:&互联网& 发布时间：
&&&&temp&:&temp是临时文件夹，在C:\Documents and Settings\Administrator\Local Settings\内。很多临时文件放在这里，收藏夹，浏览网页的临时文件，编辑文件等。这是根据你操作的过程进行临时保存的。
Class temp=传入的对象.getClass();
while(temp!=null){
System.out.println(temp.getName());
temp=temp.getSuperclass();

jad 能否带子目录反编译？

大哥，20多m呢！

是getRootPane()包含getContentPane(),
getContentPane()包含JScrollPane和JPanel,JSplitPane
JScrollPane和JPanel,JSplitPane包含JButton等组件吗?
另外Swing的布局方式有几种(请简单的写条语句举例)
还有如果要实现用在resize JFrame时,让某个JPanel随JFrame变化而适当变化应该怎么办?(比如JFrame是400,200 上面的JScrollPane是400,160,下面的JPanel是400,40, 当
JFrame被鼠标resize成600,400时, JScrollPane变成600,360 JPanel变为600,40 即JPanel的高度没有变, 类似于C++Builder里的一个align Client 一个align bottom
是不是要用JSplitPane能不能大概说一下
好......&nbsp最新技术文章: &&&&
请问visual age for java 与 webphere studio 的区别?
visual age for java已经不在出新版本了，WSAD是它的下一代产品。
visual age for java最多到版本4，现在WSAD已经版本5了，WTE也已经到版本5了。
