The following are mainly divided into three parts: Public Static string readtostring (String fileName) Public Static void throws FileNotFoundException Public Static List Readtostring, which is used to read a script from a LUA script, which is a

When Java reads a string from a byte stream, it converts platform-related bytes into platform-independent Unicode strings. During output, Java will convert the Unicode string to the byte stream related to the platform. If a Unicode character does not exist on a platform, ′? ′. For example, in Japanese windows, Java reads a "shift_jis" encoded

1.JAVA Properties class, in the Java.util package, the specific class is java.util.properties.The properties class inherits from the Hashtable class and implements the map interface, and it also holds the property set in the form of a key-value pair. However, the properties have a special place, that is, its keys and values are string types.The 2.properties class is a collection class that fills KeyValue key-value pairs. Loads the information in the.

above manner, and subsequent reads are read in the cache, and if the configuration is modified during this period, it cannot be synchronized in real time.ResourceBundle has two subclasses listresourcebundle and propertyResourceBundle, which are actually handled using propertyResourceBundle when reading the properties file.Off Topic:ResourceBundle is primarily used to address internationalization and localization issues. The information for each langu

When we use MyBatis to operate the underlying database, we need to use the XML configuration file, generally we put the configuration file and DAO in the same directory.However, when using idea to manipulate the MAVEN project, we may encounter a mapper.xml file that cannot be read to the DAO.The simple solution is as f

Java read files can be used with byte stream and character stream. Since a Chinese character accounts for two bytes, if there is a Chinese character in the configuration file, it will be garbled if it is read with a byte stream. Character streams are not garbled.The configuration f
