Java: splitting the filename into a base and extension

Question

Is there a better way to get file basename and extension than something like

File f = ...
String name = f.getName();
int dot = name.lastIndexOf(\'.\');
Strin         


        

Answer 1

Old question but I usually use this solution:

import org.apache.commons.io.FilenameUtils;

String fileName = "/abc/defg/file.txt";

String basename = FilenameUtils.getBaseName(fileName);
String extension = FilenameUtils.getExtension(fileName);
System.out.println(basename); // file
System.out.println(extension); // txt (NOT ".txt" !)
