A sample program of ZipOutputStream and ZipInputStream. This code is ported from Hishidama's Java Zip File Memo. See http://www.ne.jp/asahi/hishidama/home/tech/java/zip.html
import java.io._
import java.util.zip.ZipEntry
import java.util.zip.ZipOutputStream
import java.util.zip.ZipInputStream
def encode(zos: ZipOutputStream, files: Seq[File]) {
for (f <- files) {
if (f.isDirectory) {
encode(zos, f.listFiles)
} else {

sasaki-shigeo / gzip-sample.scala
Last active August 26, 2019 14:06
A sample code of gzip in Scala. The API of gzip is defined in the package java.util.zip that provides GZIPOutputStream and GZIPInputStream, the subclasses of DeflatterOutputStream and InflatterInputStream, respectively. GZIPOutputStream compresses data into a given output stream and GZIPInputStream decompresses data from an input one.
import java.io._
import java.util.zip._
val pi = new PipedInputStream
val po = new PipedOutputStream(pi)
val zo = new GZIPOutputStream(po)
val zi = new GZIPInputStream(pi)
val w = new PrintWriter(zo)
val r = new BufferedReader(new InputStreamReader(zi))
