示例1: isCompatIPv4Address
import java.net.Inet6Address; //導入方法依賴的package包/類
/**
* Evaluates whether the argument is an IPv6 "compat" address.
*
* <p>An "IPv4 compatible", or "compat", address is one with 96 leading bits of zero, with the
* remaining 32 bits interpreted as an IPv4 address. These are conventionally represented in
* string literals as {@code "::192.168.0.1"}, though {@code "::c0a8:1"} is also considered an
* IPv4 compatible address (and equivalent to {@code "::192.168.0.1"}).
*
* <p>For more on IPv4 compatible addresses see section 2.5.5.1 of
* <a target="_parent" href="http://tools.ietf.org/html/rfc4291#section-2.5.5.1">RFC 4291</a>.
*
* <p>NOTE: This method is different from {@link Inet6Address#isIPv4CompatibleAddress} in that it
* more correctly classifies {@code "::"} and {@code "::1"} as proper IPv6 addresses (which they
* are), NOT IPv4 compatible addresses (which they are generally NOT considered to be).
*
* @param ip {@link Inet6Address} to be examined for embedded IPv4 compatible address format
* @return {@code true} if the argument is a valid "compat" address
