OrientDB graph: How to use Java API to create a new Record?

Question

I know how to create an Record with the Web GUI of OrientDB. How am I able to create a New Record with the Java API? This is what I have done with the GUI so far.

You can download the full version of the picture here

This is my code so far but my knowledge is to low. I just know how to handle Vertex.

    OrientGraphFactory ogf = new OrientGraphFactory(
            "plocal:/home/paulkalkbrenner/Dokumente/odb/databases/ConnectER", "admin", "admin");
    OrientGraph og = ogf.getTx();

    try {
        System.out.println("message bevor vertex");

        Vertex relation0_vertex = og.addVertex(null);
        relation0_vertex.setProperty("Lastname", rel0);

        //System.out.println("Features = " + og.getFeatures());
        for (Vertex v : og.getVertices()) {
            System.out.println(v.getProperty("Lastname"));
        }
    }
    finally {
        og.shutdown();
    }

try this code

OrientGraphFactory ogf = new OrientGraphFactory(
        "plocal:/home/paulkalkbrenner/Dokumente/odb/databases/ConnectER", "admin", "admin");
    OrientGraph og = ogf.getTx();

    OClass cl=og.createVertexType("Person", "V");
    cl.createProperty("LastName", OType.STRING);

    OrientVertex v1=og.addVertex("class:Person");
    v1.setProperties("Lastname","Alessandro");

    for (Vertex v : og.getVertices()) {
        System.out.println(v.getProperty("Lastname"));
    }

    og.shutdown();

you mean the setProperties creates a new Record?

Alessandro Rota Over a year ago

with OrientVertex v1=og.addVertex("class:Person") the new vertex of type Person is created and with v1.setProperties("Lastname","Alessandro") is set the property Lastname

user4628051 Over a year ago

so you mean when I create a new Record with the GUI and put in Alessandro, it is the same as setProperties("Lastname","Alessandro") ?

when you create a new Record with the GUI and put in Alessandro ,it is the same as og.addVertex("class:Person").setProperties("Lastname","Alessandro");
