If you often need to modify a string, such as inserting, deleting, stitching, and so on, it is more appropriate to use Sringbuffer, because stringbuffer in string processing is not to generate new objects in memory because of the string class.The StringBuffer class has many of the same methods as the string class, which are functionally the same as in string, and StringBuffer is thread-safe and can be used conveniently in multithreaded programs. But the execution efficiency of the program is rel

Android submits data to the server in four ways In Android application development, data is often submitted to the server and obtained from the server.

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
