ZipOutputStream public ZipOutputStream(OutputStream out) Creates a new ZIP output stream. The UTF-8 charset is used to encode the entry names and comments. Class ZipOutputStream This is a DeflaterOutputStream that writes the files into a zip archive one after another. It has a special method to start a new zip entry. The java.util.zip.ZipOutputStream.putNextEntry(ZipEntry e) method 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

public class BufferedOutputStream extends FilterOutputStream The class implements a buffered output stream. By setting up such an output stream, an application can write bytes to the underlying output stream without necessarily causing a call to the underlying system for each byte written.

Jul 06, 2020 · while ((len = stream.read(buffer)) > 0) { bos.write(buffer, 0, len); } In the second while loop, we read the entries and write them to the output stream. In this tutorial, we have presented the Java ZipInputStream class. We have created two examples to read a ZIP file and to decompress a ZIP file. List all Java tutorials. Apr 27, 2015 · Following on from one of our popular articles on 1 we"ve put together a new article on how to create a zip archive using Java. The below example uses ZipOutputStream to create a zip file from all the items in a directory.

Zip files are written slightly differently to a normal stream in that each entry is put into the stream one at a time. using (ZipOutputStream OutputStream = new ZipOutputStream(File.Create(OutputFilePath))) { // Define the compression level // 0 - store only to 9 - means best compression OutputStream.SetLevel(CompressionLevel); byte[] buffer = new byte[4096]; foreach (string file in filenames) { // Using GetFileName makes the result compatible with XP // as the Sep 14, 2007 · Public Sub zip(ByVal srcFile As String, ByVal dstFile As String, ByVal bufferSize As Integer) Dim fileStreamIn As New FileStream(srcFile, FileMode.Open, FileAccess.Read) Dim fileStreamOut As New FileStream(dstFile, FileMode.Create, FileAccess.Write) Dim zipOutStream As New ZipOutputStream(fileStreamOut) Dim buffer(bufferSize) As Byte Dim entry As New ZipEntry(Path.GetFileName(srcFile)) zipOutStream.PutNextEntry(entry) Dim size As Integer Do size = fileStreamIn.Read(buffer, 0, buffer.Length
