Nope, Already have

change all exeptions to java.io.exeption then...

Those must be caught errors are saying you need to put those parts in try-catch statements.

Code:

import java.io.*;
import java.net.URL;
import java.net.URLConnection;
import java.util.Enumeration;
import java.util.zip.ZipEntry;
import java.util.zip.ZipFile;

    public Update(String s, String s1, String s2)

                    }
                    (new File((new StringBuilder()).append(homeDir).append(zipentry.getName()).toString())).mkdir();
                } else

}

I likely missed some parts, but that should give you an idea what you need to do.
Good luck
