从完整路径名中提取文件名（不带扩展名）

Posted 2021-02-27

public static String getFileNameWithoutExtension(String fileName) {
        File tmpFile = new File(fileName);
        tmpFile.getName();
        int whereDot = tmpFile.getName().lastIndexOf('.');
        if (0 < whereDot && whereDot <= tmpFile.getName().length() - 2 ) {
            return tmpFile.getName().substring(0, whereDot);
            //extension = filename.substring(whereDot+1);
        }    
        return "";
    }
