import com.google.common.net.InetAddresses;
// Convert the short IPv6 address to a full version
InetAddress inetAddress = InetAddresses.forString(shortIPv6); 
return inetAddress.getHostAddress();

There is no method in the standard Java libraries to do that.

The IPAddress Java library has methods to produce those formats and various other string formats.

Here is a code sample:

    IPAddressString addrString = new IPAddressString("2001:cdba::3257:9652");
    IPAddress addr = addrString.getAddress();
    String string = addr.toFullString();
    System.out.println(string);
    string = addr.toCanonicalString();
    System.out.println(string);

The output is:

2001:cdba:0000:0000:0000:0000:3257:9652
2001:cdba::3257:9652
