Read a .Z file (unix compresses file) in Java
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开发者_如何学Python 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
You can use 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
For a maintained alternative, try Apache Commons-Compress.
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 );
}
