What's that: ZipException: incorrect data check ??

Question

Hi,
I'm still trying to write a String compressor, and I got one working right now, but
when I use it with certain patterns, I get the ZipException.
Any ideas??
public final static String enc(String what)
     try
          ByteArrayOutputStream out = new ByteArrayOutputStream();
          DeflaterOutputStream dos = new DeflaterOutputStream(out,new Deflater(Deflater.BEST_SPEED,false));
          dos.write(what.getBytes("UTF8"));
          dos.finish();
          dos.flush();
          dos.close();
          return out.toString();
     }catch(Exception e)
          e.printStackTrace();
          return "";
public final static String dec(String what)
     try
          ByteArrayOutputStream out = new ByteArrayOutputStream();
          ByteArrayInputStream in = new ByteArrayInputStream(what.getBytes());
          InflaterInputStream iis = new InflaterInputStream(in,new Inflater(false));
          byte[] buffer = new byte[1024];
          int offset = -1;
          while((offset = iis.read(buffer)) != -1)
               out.write(buffer, 0, offset);
          iis.close();
          return out.toString("UTF8");
     }catch(Exception e)
          e.printStackTrace();
          return "";
}For tests:
        // Exception
        String test = "abcdefghijklmnopqrstuvwxyz";
        System.out.println(test);
        System.out.println(enc(test));
        System.out.println(dec(enc(test)));
        // works perfectly.
        test = "Eu m� duc la pia�� �i cup�r fasole";
        System.out.println(test);
        System.out.println(enc(test));
        System.out.println(dec(enc(test)));

Hmm, maybe I'll get some feedback if i post it unformatted ??
public final static String enc(String what)
try
ByteArrayOutputStream out = new ByteArrayOutputStream();
DeflaterOutputStream dos = new DeflaterOutputStream(out,new Deflater(Deflater.BEST_SPEED,false));
dos.write(what.getBytes("UTF8"));
dos.finish();
dos.flush();
dos.close();
return out.toString();
}catch(Exception e)
e.printStackTrace();
return "";
public final static String dec(String what)
try
ByteArrayOutputStream out = new ByteArrayOutputStream();
ByteArrayInputStream in = new ByteArrayInputStream(what.getBytes());
InflaterInputStream iis = new InflaterInputStream(in,new Inflater(false));
byte[] buffer = new byte[1024];
int offset = -1;
while((offset = iis.read(buffer)) != -1)
out.write(buffer, 0, offset);
iis.close();
return out.toString("UTF8");
}catch(Exception e)
e.printStackTrace();
return "";
For tests:
// Exception
String test = "abcdefghijklmnopqrstuvwxyz";
System.out.println(test);
System.out.println(enc(test));
System.out.println(dec(enc(test)));
// works perfectly.
test = "Eu m� duc la pia�� �i cup�r fasole";
System.out.println(test);
System.out.println(enc(test));
System.out.println(dec(enc(test)));
