In Qt, we sometimes need to write some parameters to the XML file, so that we can read it later, like an archive read operation, for example, we want to generate the following XML file:XML version= "1.0" encoding= "UTF-8"?>Parameters> para1>1para1> Para2>2Para2> Par

There are two ways to parse XML files, one is to use DOM to parse, this way to write code more trouble, for the first programmers are more prone to problems; the second is to use the DOM4J package to parseWhen you want to use the DOM4J package, you must first introduce the package Copy Code code as follows:

Java InputStream are widely used when performing IO, such as datainputstream.readint and so on. In fact, these highly encapsulated interfaces are incredibly slow. I have a project startup need to read about 90MB dictionary files, with DataInputStream time consuming more than 3 seconds, swap with Java.nio Packet direct operation memory byte, can accelerate to 300ms around, a full speed 10 times times!

When reading a file in Java code, it is sometimes important to keep the file in its original format (mainly to keep line wrapping). The implementation of the code is fairly straightforward.private static void ReadFile () {StringBuilder sb = new StringBuilder (); String data;

The question about how to read and write TXT files in Java is often asked during the interview. Do not understand or be unfamiliar with the comrades, but remember it!
