The easiest way to find out how to use the Java API equivalent of a REST call is to simply look up the RestAction class. In this case:
https://github.com/elasticsearch/elasticsearch/blob/master/src/main/java/org/elasticsearch/rest/action/admin/indices/alias/get/RestGetIndicesAliasesAction.java<https://github.com/elasticsearch/elasticsearch/blob/master/src/main/java/org/elasticsearch/rest/action/admin/indices/alias/get/RestGetIndicesAliasesAction.java?source=c> I am on version 0.90.2 and I have been using client.admin().cluster().state(new ClusterStateRequest()).actionGet().getState().getMetaData().aliases() which should be equivalent to yours.
