The previous properties article has described the basic usage of the Java configuration file class properties, and when viewing the Help documentation for the JDK, there are also two methods in the Properties class LoadFromXML (InputStream) and S Toretoxml (OutputStream, String, String), the XML in the method name is not difficult to determine that the two methods are r
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! Let's take a look at the specific implementation!
