file - How to get the filename without the extension in Java?

Question

Can anyone tell me how to get the filename without the extension? Example:

fileNameWithExt = "test.xml";
fileNameWithOutExt = "test";

Answer 1

If you, like me, would rather use some library code where they probably have thought of all special cases, such as what happens if you pass in null or dots in the path but not in the filename, you can use the following:

import org.apache.commons.io.FilenameUtils;
String fileNameWithOutExt = FilenameUtils.removeExtension(fileNameWithExt);
