Keep doing it until whole file is processed.

Using InputStream and BufferedInputStream, we read the uncompressed bytes into a byte buffer to then use FileOutputStream to write it to a file.

Each ZipEntry instance has the compressed and uncompressed size information, the name, and the input stream of the uncompressed bytes.

ZipEntry class represents an entry in the zip file – either file or directory.

zip file and is used to access its information. ('Written :' + entry.getName()) īelow listed things are happening in sequence in the above example. Path uncompressedFilePath = fileSystem.getPath(uncompressedFileName) įileOutputStream fileOutput = new FileOutputStream(uncompressedFileName) String uncompressedFileName = uncompressedDirectory + entry.getName() InputStream is = file.getInputStream(entry) īufferedInputStream bis = new BufferedInputStream(is)

('Creating Directory:' + uncompressedDirectory + entry.getName()) įiles.createDirectories(fileSystem.getPath(uncompressedDirectory + entry.getName())) If directory then create a new directory in uncompressed folder String uncompressedDirectory = 'uncompressed/' įiles.createDirectory(fileSystem.getPath(uncompressedDirectory))

Try(ZipFile file = new ZipFile('files.zip'))įileSystem fileSystem = FileSystems.getDefault() Then uses FileOutputStream to write all the files into file system. If we find a file entry, we write the decompressed file. If we find a directory entry, we create a new directory. The example opens a zip file and starts traversing the files in a similar manner used in walking a directory tree. The Example uses ZipInputStream to read a ZipFile and then read all the ZipEntry one by one. Example of java code to uncompress and extract files from a compressed zip file using package.

If we find a file entry, we write the decompressed file. Once you have downloaded the 5 zip files, they need to be placed in the following folders found at C:UsersDownloadsMathWorksSupportPackages.
