Error occured handelling zip file

Question

hi guys
i am executing the following source code to copy .zip file
// Java Document
import java.io.*;
import java.util.zip.*;
public class moveZip {
public static void main (String argv[]) {
try {
final int BUFFER = 12048;
     FileOutputStream dest = new
FileOutputStream("c:\\myfigs.zip");
CheckedOutputStream checksum1 = new
CheckedOutputStream(dest, new Adler32());
ZipOutputStream out = new
ZipOutputStream(new
BufferedOutputStream(checksum1));
          byte data[] = new byte[BUFFER];
FileInputStream fis = new
     FileInputStream(argv[0]);
CheckedInputStream checksum = new
CheckedInputStream(fis, new Adler32());
ZipInputStream zis = new
ZipInputStream(new
BufferedInputStream(checksum));
ZipEntry entry;
while((entry = zis.getNextEntry()) != null) {
System.out.println("Extracting: " +entry);
// int count;
//byte data1[] = new byte[BUFFER];
// write the files to the disk
               out.putNextEntry(entry);
int count;
while((count = zis.read(data, 0,
BUFFER)) != -1) {
out.write(data, 0, count);
zis.close();
          out.close();
System.out.println("Checksum:"+checksum.getChecksum().getValue());
} catch(Exception e) {
e.printStackTrace();
But i am getting error like:
C:\kkkk>java moveZip temp.zip

Answer 1

the file is at its location....... not password protected.... and i've thought of all the "half-a-dozen things" u haven't thought of...
thanks anyway for taking the pain to reply.
u needn't have replied if it was bugging u so.
Maybe the zip file isn't at that location. Maybe it
didn't get completely downloaded. Maybe downloading it
puts permissions on it that don't allow you to open
it. Maybe it's password-protected. Maybe half-a-dozen
things I haven't thought of yet. Did you check any of
those obvious things? Can you open the file yourself
with a zip utility?
