Usage

From source file:Main.java

public static void main(String[] argv) throws Exception {
    ZipFile zf = new ZipFile("a.zip");
    Enumeration<? extends ZipEntry> files = zf.entries();

    while (files.hasMoreElements()) {
        ZipEntry ze = files.nextElement();

        System.out.println("Decompressing " + ze.getName());
        System.out.println(//from  w w w .j a  v  a2  s .c o  m
                "  Compressed Size: " + ze.getCompressedSize() + "  Expanded Size: " + ze.getSize() + "\n");

        BufferedInputStream fin = new BufferedInputStream(zf.getInputStream(ze));
