BE THE CODER > Java > Zip Utilities

The following example shows how to iterate through the entries of a zip file. We can check whether the current entry is file or directory using entry.isDirectory() method. For files we can get the actual file size and compressed file size in bytes using entry.getSize() and entry.getCompressedSize() methods.
