The method pathCompinent() is used to remove the file information from a filename and return only its path component. This method requires a single parameter i.e. the file name and it returns the path component only of the file name.
A program that demonstrates this is given as follows −
import java.io.File; public class Demo { public static String pathComponent(String fname) { int pos = fname.lastIndexOf(File.separator); if (pos > -1) return fname.substring(0, pos); else return fname; } public static void main(String[] args) { System.out.println(pathComponent("c:\\JavaProgram\\demo1.txt")); } }
The output of the above program is as follows −
c:\JavaProgram
Now let us understand the above program.
The method pathCompinent() is used to remove the file information from a file name and return only its path component. A code snippet that demonstrates this is given as follows −
public static String pathComponent(String fname) { int pos = fname.lastIndexOf(File.separator); if (pos > -1) return fname.substring(0, pos); else return fname; }
The method main() prints the path component of the file name that was returned by the method pathComponent(). A code snippet that demonstrates this is given as follows −
public static void main(String[] args) { System.out.println(pathComponent("c:\\JavaProgram\\demo1.txt")); }
