Java ZipInputStream. ZipInputStream is a Java class that implements an input stream filter for reading files in the ZIP file format. It has support for both compressed and uncompressed entries. I am zipping a large number (about 300,000) of small text files using Java. I am running out of heap space during the operation and I think that this is because the zipping process uses a hashtable which becomes too large. In java, ZipOutputStream class is used to zip the file. Source file can be any file and that will be written in zip file. ZipOutputStream has a method public void putNextEntry(ZipEntry e) throws IOException That takes input ZipEntry class. ZipEntry represents a zip file entry. putNextEntry begins writing new zip file and sets the start point. Begins writing a new ZIP file entry and positions the stream to the start of the entry data. Closes the current entry if still active. The default compression method will be used if no compression method was specified for the entry, and the current time will be used if the entry has no set modification time.
