Java method to obtain the absolute path under the current path, or the absolute path of a file

Java to obtain the absolute path under the current path. Or the absolute path of a file.

Import java.net. URL; import java. security. codeSource; import java. security. protectionDomain; public class TestPath {public static void main (String [] args) {ProtectionDomain domain = TestPath. class. getProtectionDomain (); CodeSource codeSource = domain. getCodeSource (); URL location = codeSource. getLocation (); String path = location. getPath (); System. out. println (path); URL url = TestPath. class. getClassLoader (). getResource ("log4j. xml "); String aurl = url. getPath (); System. out. println (aurl); URL pathUrl = TestPath. class. getResource (""); System. out. println (pathUrl. getPath ());}}

 

There are two main types, which are obtained through the current class.
