java.util.zip.ZipInputStream (JDK 1.1)

This class is a subclass of InflaterInputStream that reads the entries of a ZIP file in sequential order. A ZipInputStream is created by specifying the InputStream from which it is to read the contents of the ZIP file. Once the ZipInputStream is created, the getNextEntry() method is used to begin reading of data from the next entry in the ZIP file. This method must be called before read() is called to begin reading of the first entry. Note that getNextEntry() returns a ZipEntry object that describes the entry being read. Also note that getNextEntry() returns null when there are no more entries to be read from the ZIP file.

The read() methods of ZipInputStream read until the end of the current entry and then return -1 indicating that there are no more data to read. To continue with the next entry in the ZIP file, you must call getNextEntry() again. Similarly, the skip() method only skips bytes within the current entry. closeEntry() can be called to skip the remaining data in the current entry, but it is usually easier simply to call getNextEntry() to begin the next entry.
