你可以使用path = C:\Hello\AnotherFolder\TheFileName.PDF

String strPath = path.substring(path.lastIndexOf("\\")+1, path.length());

只需使用File.getName()

File f = new File("C:\\Hello\\AnotherFolder\\The File Name.PDF");
System.out.println(f.getName());

使用String方法:

  File f = new File("C:\\Hello\\AnotherFolder\\The File Name.PDF");  
System.out.println(f.getAbsolutePath().substring(f.getAbsolutePath().lastIndexOf("\\")+1));

你可以使用path = C:\Hello\AnotherFolder\TheFileName.PDF

String strPath = path.substring(path.lastIndexOf("\\")+1, path.length());

考虑Java是多平台的情况:

int lastPath = fileName.lastIndexOf(File.separator);
if (lastPath!=-1){
    fileName = fileName.substring(lastPath+1);
}

您可以使用FileInfo对象来获取文件的所有信息。

    FileInfo f = new FileInfo(@"C:\Hello\AnotherFolder\The File Name.PDF");
    MessageBox.Show(f.Name);
    MessageBox.Show(f.FullName);
    MessageBox.Show(f.Extension );
    MessageBox.Show(f.DirectoryName);

使用Java regex *提取文件名。

public String extractFileName(String fullPathFile){
        try {
            Pattern regex = Pattern.compile("([^\\\\/:*?\"<>|\r\n]+$)");
            Matcher regexMatcher = regex.matcher(fullPathFile);
            if (regexMatcher.find()){
                return regexMatcher.group(1);
            }
        } catch (PatternSyntaxException ex) {
            LOG.info("extractFileName::pattern problem <"+fullPathFile+">",ex);
        }
        return fullPathFile;
    }
