Examples of java.util.zip.ZipInputStream.skip()

java.util.zip.ZipInputStream.skip()
Skips specified number of bytes in the current ZIP entry. @param n the number of bytes to skip @return the actual number of bytes skipped @exception ZipException if a ZIP file error has occurred @exception IOException if an I/O error has occurred @exception IllegalArgumentException if n < 0

            if (entry==null) {
                break;
            }


            while (zin.available()>0) {
                zin.skip(zin.available());
            }
        }
