How can I convert byte array to ZIP file

Question

I am trying to convert an array of bytes into a ZIP file. I got bytes using the following code:

byte[] originalContentBytes= new Verification().readBytesFro         


        

Answer 1

You probably are looking for code like this:

ZipInputStream z = new ZipInputStream(new ByteArrayInputStream(buffer))

now you can get the zip file contents via getNextEntry()

Answer 2

To get the contents from the bytes you can use

ZipInputStream zipStream = new ZipInputStream(new ByteArrayInputStream(bytes));
ZipEntry entry = null;
while ((entry = zipStream.getNextEntry()) != null) {

    String entryName = entry.getName();

    FileOutputStream out = new FileOutputStream(entryName);

    byte[] byteBuff = new byte[4096];
    int bytesRead = 0;
    while ((bytesRead = zipStream.read(byteBuff)) != -1)
    {
        out.write(byteBuff, 0, bytesRead);
    }

    out.close();
    zipStream.closeEntry();
}
zipStream.close();
