There are no examples for this, but you would use the Node Management services provided by OpcUaClient:

• OpcUaClient::addNodes
• OpcUaClient::addReferences
• OpcUaClient::deleteNodes
• OpcUaClient::deleteReferences

You should read about these services in Part 4 of the OPC UA spec: https://reference.opcfoundation.org/v104/Core/docs/Part4/5.7.1/

Thanks for your responce! I started your ExampleServer class and tried to adding 1 new Variable node(Float) using WriteExample class as example. I also create all neccesery object to add node, but server response is: StatusCode{name=Bad_NotSupported, value=0x803D0000, quality=bad}.
Code in WriteExample:
client.connect().get();
ExpandedNodeId parentNodeId = new ExpandedNodeId(UShort.valueOf(2),null, "HelloWorld/ScalarTypes");
NodeId referenceTypeId = new NodeId(Unsigned.ushort(0), Unsigned.uint(10));
ExpandedNodeId requestedNewNodeId = new ExpandedNodeId(UShort.valueOf(2),null, "HelloWorld/ScalarTypes/TestFLOATNodee");
QualifiedName browseName = new QualifiedName(2,"TestFLOATNodee");
NodeClass nodeClass = NodeClass.Variable;
ExtensionObject nodeAttributes = new ExtensionObject(new ByteString("4".getBytes()),referenceTypeId);
ExpandedNodeId typeDefinition = new ExpandedNodeId(UShort.valueOf(2),null, "HelloWorld/ScalarTypes/Float");
AddNodesItem addNodesItem = new
AddNodesItem(parentNodeId,referenceTypeId,requestedNewNodeId,browseName,nodeClass,nodeAttributes,typeDefinition);
List listNodes = new ArrayList<>();
listNodes.add(addNodesItem);
CompletableFuture responce = client.addNodes(listNodes);
AddNodesResponse nodesresponse = responce.get();
AddNodesResult[] results = nodesresponse.getResults();
System.out.println(results[0].getStatusCode());
future.complete(client);
Thanks for you patience... maybe i so bad...

The example server does not support these services. You’ll have to find one that does or implement them yourself.
