== Create ZipInputStream from FileInputStream ==



<source lang="java">
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import java.util.zip.ZipEntry;
import java.util.zip.ZipInputStream;
public class MainClass {
public static void main(String[] args) throws IOException {
for (int i = 0; i < args.length; i++) {
FileInputStream fin = new FileInputStream(args[i]);
ZipInputStream zin = new ZipInputStream(fin);
ZipEntry ze = null;
while ((ze = zin.getNextEntry()) != null) {
System.out.println("Unzipping " + ze.getName());
FileOutputStream fout = new FileOutputStream(ze.getName());
for (int c = zin.read(); c != -1; c = zin.read()) {
fout.write(c);
}
zin.closeEntry();
fout.close();
}
zin.close();
}
}
}</source>



== Decompress a zip file using ZipInputStream ==



<source lang="java">
import java.io.BufferedInputStream;
import java.io.BufferedOutputStream;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.util.zip.ZipEntry;
import java.util.zip.ZipInputStream;
public class Main {
public static void main(String[] args) throws Exception {
String zipname = "data.zip";
FileInputStream fis = new FileInputStream(zipname);
ZipInputStream zis = new ZipInputStream(new BufferedInputStream(fis));
ZipEntry entry;
while ((entry = zis.getNextEntry()) != null) {
System.out.println("Unzipping: " + entry.getName());
int size;
byte[] buffer = new byte[2048];
FileOutputStream fos = new FileOutputStream(entry.getName());
BufferedOutputStream bos = new BufferedOutputStream(fos, buffer.length);
while ((size = zis.read(buffer, 0, buffer.length)) != -1) {
bos.write(buffer, 0, size);
}
bos.flush();
bos.close();
}
zis.close();
fis.close();
}
}</source>



== Read zip file with ZipInputStream ==



<source lang="java">
import java.io.FileInputStream;
import java.util.zip.ZipEntry;
import java.util.zip.ZipInputStream;
class ZipReader {
public static void main(String[] args) throws Exception {
ZipInputStream zis = null;
FileInputStream fis = new FileInputStream(args[0]);
zis = new ZipInputStream(fis);
ZipEntry ze;
while ((ze = zis.getNextEntry()) != null)
System.out.println(ze.getName());
}
}</source>



== Unzip using the ZipInputStream ==



<source lang="java">
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import java.util.zip.ZipEntry;
import java.util.zip.ZipInputStream;
public class MainClass {
public static void main(String[] args) throws IOException {
for (int i = 0; i < args.length; i++) {
FileInputStream fin = new FileInputStream(args[i]);
ZipInputStream zin = new ZipInputStream(fin);
ZipEntry ze = null;
while ((ze = zin.getNextEntry()) != null) {
System.out.println("Unzipping " + ze.getName());
FileOutputStream fout = new FileOutputStream(ze.getName());
for (int c = zin.read(); c != -1; c = zin.read()) {
fout.write(c);
}
zin.closeEntry();
fout.close();
}
zin.close();
}
}
}</source>
