Adler32.java: Make private variables really private

2000-08-20  Mark Wielaard  <mark@klomp.org>

    * java/util/zip/Adler32.java: Make private variables really private
    * java/util/zip/CRC32.java: Make private variables really private
    * java/util/zip/CheckedInputStream.java: skip() could skip to much bytes
    * java/util/zip/InflaterInputStream.java: skip() could skip to much bytes
    * java/util/zip/ZipEntry.java: setCompressedSize() didn't check input
    * java/util/zip/ZipFile.java: size() new 1.2 method
    * java/util/zip/ZipInputStream.java: Use createZipEntry not new ZipEntry.
    since 1.2 available() always returns just 1 or 0 when closed
