    Exclamation Password protected zip files and Java

    Hi all. Sorry if this is in wrong section. Please move to relevant section and I will make a note in future :)

    So i am quite new to java and have been thrown in the deep end. I have a requirement:-

    I need to write a method to check whether

    A: A zip file is password protected AND
    B: The password is "password".

    I am using zip4j library.

    The code I have so far is below but I am sure it is wrong. Can someone please help me? I would be very grateful...


    import java.io.IOException;
    import net.lingala.zip4j.core.ZipFile;
    import net.lingala.zip4j.exception.ZipException;
    import net.lingala.zip4j.io.Zip4jInputStream;

    public class Main {
    public boolean isZipProtected(InputStream zipFile);
    public static void main(String[] args) throws IOException {
    try{
    ZipFile zipFile = new ZipFile("c:\\zip\\FILENAME.zip");

    // Check to see if the zip file is password protected
    if (zipFile.isEncrypted()) {
    // if yes, then set the password for the zip file
    zipFile.setPassword("password");

    }
    zipFile.extractFile("*", "c:\\zip\\TEMPLOCATION\\");
    InputStream input = new FileInputStream(zipFile);
    return true;
    }catch(ZipException ex){
    System.out.println("error "+ ex );
    }
    }

    }

    Does the above code work?
    If not then what errors/exceptions are you getting, complete with any stack trace and highlighting the line causing the problem.
    Please do not ask for code as refusal often offends.
