I'm fairley new to programming in general being a fresh IT graduate.
Some software I am developing needs to be able to compress a folder in to a .zip file and later extract it while maintaining its file structure.
I am able to do this but extracting the file takes far to long, a file that takes a few seconds for winzip to extract takes far longer in my app.
I've tried google and have failed to find the reason for this. My code is as follows:
public void unzipFolder( String startingZip, String destinationFolder ) {
try {
ZipFile zipFile = new ZipFile(startingZip);
Enumeration< ? extends ZipEntry> zipCount = zipFile.entries();
String dir = destinationFolder;
while( zipCount.hasMoreElements() ) {
ZipEntry item = (ZipEntry) zipCount.nextElement();
if (item.isDirectory()) {
File newdir = new File(dir + File.separator + item.getName());
newdir.mkdir();
} else {
String newfilePath = dir + File.separator + item.getName();
File newFile = new File(newfilePath);
if (!newFile.getParentFile().exists()) {
newFile.getParentFile().mkdirs();
}
InputStream is = zipFile.getInputStream(item);
FileOutputStream fos = new FileOutputStream(newfilePath);
int ch;
while( (ch = is.read()) != -1 ) {
fos.write(ch);
}
is.close();
fos.close();
}
}
zipFile.close();
} catch (Exception e) {
System.out.println(e);
}
}Any help would be greatly appreciated ;p
