An exampes that demonstrates how we update multiple fields on elastic search document

Map<String, Object> updateObject = new HashMap<String, Object>();
updateObject.put("field1", "updated value for fields1");
updateObject.put("field2", "updated value for fields2");
updateObject.put("field3", "updated value for fields3");            
Boolean meessage = client.prepareUpdate("indexName","indextype","documentId").setDoc(updateObject).setRefresh(true).execute().actionGet();

indexName will be your index name IndexType will be your index type documentId will be your documentId which is going to update client is your ElasticSeach client for JAVA API

I think your question is how to update multiple fields using JAVA api.

For that use BulkRequestBuilder

BulkRequestBuilder bulkRequest = client.prepareBulk();

bulkRequest.add(client.prepareUpdate("indexName","indextype","documentId") 
                .setScript("ctx._source.field1=" + newValueField1));

bulkRequest.add(client.prepareUpdate("indexName","indextype","documentId") 
                .setScript("ctx._source.field2=" + newValueField2));

BulkResponse bulkResponse = bulkRequest.execute().actionGet();

By this you can update multiple values within document
