Question

I am trying to unzip a zipfile with password protection. I know there is a java library named “zip4j” that could help me. But I am failing to open the zip4j website to see the tutorial.

Try the following and make sure you are using the most recent Zip4j library (1.3.1):

String source = "folder/source.zip";
String destination = "folder/source/";
String password = "password";

try {
    ZipFile zipFile = new ZipFile(source);
    if (zipFile.isEncrypted()) {
        zipFile.setPassword(password);
    }
    zipFile.extractAll(destination);
} catch (ZipException e) {
    e.printStackTrace();
}
