GZIPInputStream, ZipInputStream public class InflaterInputStream extends FilterInputStream This class implements a stream filter for uncompressing data in the "deflate" compression format. It is also used as the basis for other decompression filters, such as GZIPInputStream.
There is actually no way to reset a ZipInputStream, as you expect, because it does not support reset / markers, etc.But you can use ByteArrayOutputStream to buffer InputStream as byte /** * Compresses a collection of files to a destination zip file. * * @param listFiles A collection of files and directories * @param destZipFile The path of the destination zip file * @throws FileNotFoundException if file not found * @throws IOException if IO exception occurs */ public void compressFiles(List
Create a ZipInputStream, explicitly specifying whether to keep the underlying stream open. See the documentation for the ZipInputStream(Stream) constructor for a discussion of the class, and an example of how to use the class. ZipInputStream ( String fileName) : System: Create a ZipInputStream, given the name of an existing zip file.
ZipInputStream(IntPtr, JniHandleOwnership) ZipInputStream(IntPtr, JniHandleOwnership) A constructor used when creating managed representations of JNI objects; called by the runtime. ZipInputStream(Stream) ZipInputStream(Stream) Constructs a new ZipInputStream to read zip entries from the given input stream. GZIPInputStream, ZipInputStream public class InflaterInputStream extends FilterInputStream This class implements a stream filter for uncompressing data in the "deflate" compression format. It is also used as the basis for other decompression filters, such as GZIPInputStream. Jan 20, 2020 · Let's first have a look at a simple operation – zipping a single file. For our example here we'll zip a file named test1.txt into an archived named compressed.zip.. We'll of course first access the file from disk – let's have a look: Description. The java.util.zip.ZipInputStream.read(byte buf, int off, int len) method reads from the current ZIP entry into an array of bytes. If len is not zero, the method blocks until some input is available; otherwise, no bytes are read and 0 is returned.
Apr 11, 2019 · Below are some Java examples to convert InputStream to File. Copy InputStream to FileOutputStream manually; Apache Commons IO – FileUtils.copyInputStreamToFile Java 1.7 NIO Files.copy
However, GZipOutputStream has an internal buffer, so it doesn't write individual bytes out to the underlying stream. Depending on the underlying stream type (eg, file vs socket) and the relative sizes of the buffers, you may or may not see any difference. – parsifal Jan 22 '13 at 17:47
