I have a file in .gz format. The java class for reading this file is GZIPInputStream. 
However, this class doesn&#39;t extend the BufferedReader class of java. As a result, I am not able to read the file line by line. I need something like this

    reader  = new MyGZInputStream( some constructor of GZInputStream) 
    reader.readLine()...

I though of creating my class which extends the Reader or BufferedReader class of java and use GZIPInputStream as one of its variable.



    import java.io.BufferedReader;
    import java.io.FileInputStream;
    import java.io.FileNotFoundException;
    import java.io.IOException;
    import java.io.Reader;
    import java.util.zip.GZIPInputStream;
    
    public class MyGZFilReader extends Reader {
    
    	private GZIPInputStream gzipInputStream = null;
    	char[] buf = new char[1024];
    	                      
    	@Override
    	public void close() throws IOException {
    		gzipInputStream.close();
    	}
    
    	public MyGZFilReader(String filename)
                   throws FileNotFoundException, IOException {
            gzipInputStream = new GZIPInputStream(new FileInputStream(filename));
    	}

    	@Override
    	public int read(char[] cbuf, int off, int len) throws IOException {
    		// TODO Auto-generated method stub
    		return gzipInputStream.read((byte[])buf, off, len);
    	}
    
    }


But, this doesn&#39;t work when I use

    BufferedReader in = new BufferedReader(
        new MyGZFilReader(&quot;F:/gawiki-20090614-stub-meta-history.xml.gz&quot;));
    System.out.println(in.readLine());

Can someone advice how to proceed ..
