9200 is restful api， 9300 is java api  
now，I don't know which one to choose.  
9200 can do more than 9300  
for example，9200 can use "\_cat/indices"，but 9300 can not  
but my project is use java，  
i use both 9200 port and 9300 port in my project ？

If you are just starting out, I would recommend you use the [Java REST client](https://www.elastic.co/guide/en/elasticsearch/client/java-rest/current/index.html) which uses HTTP over port 9200 as the Java Transport client is being deprecated.
