This snippet demonstrates how to create a simple ZIP file from a byte array in memory:
To generate a ZIP archive in Java, you typically use the standard java.util.zip package. The core process involves creating a ZipOutputStream and adding individual ZipEntry objects for each file you want to include. Java Implementation Steps
