canonical path java

The user interface and operating system name the files and directories using the system-related pathname string. This class renders an abstract, system-independent view of the hierarchical path name. The abstract path name has two components:An

These few ways to get path are different in the file, so the detailed difference is below.Conceptual differences: (content from the JDK, the personal feeling of this descriptive information, only to let the understanding of the people understand

By default. * in. Only characters other than \ n can be matched, and if a string to be matched contains a carriage return newline (multiple lines), the regular expression will stop after encountering a newline character, causing the string

A regular expression is a formula that uses a pattern to match a type of string, and the regular expression consists of some ordinary characters and some metacharacters (metacharacters). Ordinary characters include uppercase and lowercase letters

Java regular expressions match multiple rowsBy default.. only characters other than \ n can be matched. If the string to be matched contains the carriage return line break (multiple lines), the regular expression stops when it encounters a line
