I'm just trying to teach myself how to use java.util.zip, but I'm struggling with one part I think. The code below is what I have so far, I'm just not sure how to actually get it to read in a zip file? Any help would be much appreciated.
import java.io.*;
import java.util.*;
import java.util.zip.*;
public class ZipExample {
public static final void copyInputStream(InputStream in, OutputStream out)
throws IOException
{
byte[] buffer = new byte[1024];
int len;
while((len = in.read(buffer)) >= 0)
out.write(buffer, 0, len);
in.close();
out.close();
}
public static final void main(String[] args) {
Enumeration <?> entries;
ZipFile zipFile;
if(args.length != 1) {
System.err.println("Usage: Unzip zipfile");
return;
}
try {
zipFile = new ZipFile(args[0]);
entries = zipFile.entries();
while(entries.hasMoreElements()) {
ZipEntry entry = (ZipEntry)entries.nextElement();
if(entry.isDirectory()) {
// Assume directories are stored super then sub
System.err.println("Extracting directory: " + entry.getName());
(new File(entry.getName())).mkdir();
continue;
}
System.err.println("Extracting file: " + entry.getName());
copyInputStream(zipFile.getInputStream(entry),
new BufferedOutputStream(new FileOutputStream(entry.getName())));
}
zipFile.close();
} catch (IOException ioe) {
System.err.println("Unhandled exception:");
ioe.printStackTrace();
return;
}
}
}
