To insert/delete, you must use mutate().

Insert using JSON:

```auto
DgraphClient.Transaction transaction = getDgraphClient().newTransaction();
DgraphProto.Mutation mutation = DgraphProto.Mutation.newBuilder()
    .setSetJson(ByteString.copyFromUtf8("[" +
        "{\"uid\":\"0x123\", \"name\":\"Tom\"}," +
        "{\"name\":\"Jane\"}]"))
    .build();
transaction.mutate(mutation);
transaction.commit();

```

However, I’m also curious how to insert data using `DgraphProto.NQuad` and how to use [blank nodes](https://docs.dgraph.io/query-language/#blank-nodes-and-uid) with dgraph4j.

can you insert edge relationship?  
DgraphClient.Transaction transaction = getDgraphClient().newTransaction();  
DgraphProto.Mutation mutation = DgraphProto.Mutation.newBuilder()  
.setSetJson(ByteString.copyFromUtf8(  
“{“uid”:“0x123”, “call”:“0x124”}”))  
.build();  
transaction.mutate(mutation);  
transaction.commit();

They have added new tests that are helpful: [https://github.com/dgraph-io/dgraph4j/blob/master/src/test/java/io/dgraph](https://github.com/dgraph-io/dgraph4j/blob/master/src/test/java/io/dgraph)

We have added some code in the tests folder which should illustrate the different scenarios. Hopefully they can guide you along in writing your own code to perform insertions.
