在Java中读取.Z文件（unix压缩文件）

发布于 2024-09-13 19:25:00 字数 390 浏览 4 评论 0原文

上述文件扩展名的解释见 http://kb.iu.edu/data/abck。 html。我想使用 java api 读取 Z 文件的内容。 ZipFile api 或 GZIPInputStream 似乎都不起作用。我可以使用 ZipFile api 打开普通的 .zip 文件。

ZipFile zf = new ZipFile("CR93H2.Z");
Enumeration entries = zf.entries();

补充一下，上述 .Z 文件在 winrar 中可以正常打开。

有谁知道它的解决方案。

谢谢

The said file extension is explained here at http://kb.iu.edu/data/abck.html. I want to use a java api to read the contents of a Z file. Neither the ZipFile api or the GZIPInputStream seem to work. I can use the ZipFile api to open normal .zip files.

ZipFile zf = new ZipFile("CR93H2.Z");
Enumeration entries = zf.entries();

To add, the said .Z file opens up fine in winrar.

Does anyone know about the solution to it.

Thanks

您可以使用 compress-j2me：

% git clone https://github.com/igorgatis/compress-j2me.git
% cd compress-j2me/src/lzc-test
% ant -q
% cd build/cmd
% echo "testdonkeyballs" | compress | java com.googlecode.compress_j2me.lzc.Main -d
testdonkeyballs

对于维护的替代方案，请尝试 Apache Commons-压缩。

我已成功使用 UncompressInputStream 读取压缩文件.java。我还没有验证逻辑是否正确，但似乎可行。

    FileInputStream fis = new FileInputStream( new File( "thefile.cfg.Z" ) );
    InputStream is = new UncompressInputStream( new BufferedInputStream( fis ) ); 
    BufferedReader reader = new BufferedReader(new InputStreamReader( is ) );
    String line = null;
    while ( ( line = reader.readLine() ) != null )
    {
        System.out.println( "line = " + line );
    }

I've had success reading compressed files with UncompressInputStream.java. I haven't verified if the logic is correct, but it seems to work.

    FileInputStream fis = new FileInputStream( new File( "thefile.cfg.Z" ) );
    InputStream is = new UncompressInputStream( new BufferedInputStream( fis ) ); 
    BufferedReader reader = new BufferedReader(new InputStreamReader( is ) );
    String line = null;
    while ( ( line = reader.readLine() ) != null )
    {
        System.out.println( "line = " + line );
    }
