3 ways to get file name without extension

Using apache commons

import org.apache.commons.io.FilenameUtils;

String fileNameWithoutExt = FilenameUtils.getBaseName(fileName);

                           OR

String fileNameWithOutExt = FilenameUtils.removeExtension(fileName);

Using Google Guava (If u already using it)

import com.google.common.io.Files;
String fileNameWithOutExt = Files.getNameWithoutExtension(fileName);

Or using Core Java

String fileName = file.getName();
int pos = fileName.lastIndexOf(".");
if (pos > 0) {
    fileName = fileName.substring(0, pos);
}
