To pay special attention to its format: such as carriage return line, the poor one may not get the correct response, as well as

Http://www.cnblogs.com/zhjp11/archive/2010/02/26/1674227.html Today, when we look at algorithm analysis, we can see a problem where we can find the largest K value in a pile of data. The name is: design a group of N numbers, and determine the maximum value of K. This is a selection problem. Of course, there are many ways to solve this problem. I searched for it online, the following method is recommended. The so-called "Nth (first) K large number problem" refers to finding the Nth (first) Order

assign the required regular expression to the pattern class: Patterncompiler orocom=new Perl5compiler (); Pattern Pattern=orocom.compile ("REGULAR EXPRESSIONS"); Patternmatcher matcher=new Perl5matcher (); But in the Java.util.regex package, we only need to generate a pattern class, the direct use of its compile () method can achieve the same effect: Pattern p = pattern.compile ("[/]+"); So it seems that Java.util.regex's construction method is simpler and easier to understand than Jakarta-oro.

, including the last row. If you use the Sniffer program to check the POST request sent by IE, you can find that the IE separator is similar to ------------------------- 7d4a6d158c9, which is a random number generated by IE, the purpose is to prevent the server from correctly identifying the start position of a file due to a separator in the uploaded file. We can write a fixed separator as long as it is complex enough. The POST code for sending the file is as follows: String [] props =... // fie
