I am curious what comparison function it applys in its' sorting function. I supposed it should be a string comparison, like strcmp function, but it is not. coz strcmp will compare ascii code of characters in string one by one, thus above sorting should like this:
abc-d.com
abca.com
abce.com
one guess is that when sorting names the special characters like "." "-" will be skipped. but still got some problem when sorting following names:
abc---d.com
abc--d.com
abc-d.com
why can linux sorting keep this order? if it skips some special characters, above names should be compared equally and maybe sorted as a random order.
confused, anybody has thought about that?
-----
p.s.
Haven't got updated here for quite a long time, coz I am back to program with c under linux and I believe it is a place for Java programmers.
-----
update:
Linux sorting compares unicode of strings 鈥?more about unicode is here

the functions openConnection() and connect() are ok, curious about that problem.
anybody has the same problem or similar problem with URLConnection?

1- Make sure u have Installed Apache 2 & PHP 5 and Java J2EE 1.5
2- download pecl-5.0.5-Win32.zip and php-java-bridge_2.0.8.zip, which will include
extra dll(s)
聽聽 - unpack pecl pkg to your extensions folder, in PHP5 its ext.
聽聽 - unpack java-Bridge to root php folder, in my case its simply C:\PHP
聽聽
Note:
1. the java-Bridge inculdes new versions of certain files like php_java.dll
聽聽 so, it would be wise to rename your old files that came with PECL pkg for example
聽聽 file_old, to rollback at anytime.
2. Don't run batch file under php-java-bridge after unpacking to php root folder, just add following lines in php.ini configure file (depends on installation fold of j2ee):
extension=php_java.dll
extension_dir = "C:\php\ext"
[java]

Reader reader = new InputStreamReader( in ); //in is an instance of class InputStream or derived classesBut the issue is sometimes we need convert a reader to inputstream, think about following scenaros:
1.聽 the original inputstream has been filtered by certian reader, now we need save back filtered content into database by inputstream: we can not use original inputstream but filtered stream which can only get from your reader.
2.聽 Given a class who contains a reader to access a streaming content after complex parsering or downloading, we want to utilize the streaming content in this class while not repeating complex operations for content analysis, so we need employ some wrapper methods to get inputstream from reader.
-- Solution:
1. write own InputStream implementation, such as following:
class MyInputStream extends InputStreamNote: Applications that need to define a subclass of
{
private Reader rd;
public MyInputStream(Reader rd)
{
super();
this.rd = rd;
}
聽
聽
// implement the read() method to make this all work
publicint read()
{
int t = rd.read();
// you can do your processing on the inputReader here
// fiddle with the values and return
return t;
聽
}
}
InputStream
must always provide a method that returns the next byte of input. (refer to http://java.sun.com/j2se/1.4.2/docs/api/java/io/InputStream.html)
-- anything else? BTW, for parsering xml-based input stream by SAX, I am glad to see that the inputSource constructor can take either InputStream or Reader (refer to http://java.sun.com/j2se/1.4.2/docs/api/org/xml/sax/InputSource.html)
