Poodle is a vulnerability that implicitly affects to SSLv3. Then for check it, you have a lot of ways to do it.
First way with nmap:
$ nmap -sT -p443 --script ssl-poodle <target>
Second way with nmap:
$ nmap -sT -p443 --script ssl-enum-ciphers <target>
If here you have SSLv3 ciphers then you are vulnerable.
Other way, with sslscan:
$ sslscan <domain>
Other way, with openssl:
$ openssl s_client -ssl3 -connect host:port
If connect, you are vulnerable
Other way, using SSL Test Server of Qualys.
And in Java, you can try to connect SSLv3, if the server accept your connection, then you are vulnerable.
System.setProperty("https.protocols", "SSLv3");
Set the protocol SSLv3 before the connection.
