// add dasratha's son.
Vertex ram = addSon("fname", "ram", graph,
das);
Vertex laxman = addSon("fname", "laxman",
graph, das);
Vertex bharat = addSon("fname", "bharat",
graph, das);
Vertex shatrugna = addSon("fname",
"shatrugna", graph, das);
private static Vertex addSon(String
propertyName, String value, TitanGraph graph,
Vertex

father)

{

Vertex son = add(propertyName, value,

graph);

graph.addEdge(null, son, father, "son

of");

return son;

}

3. Repeat step 2 for ram , laxman , bharat , and shatrugna :

// ram's son
addSon("fname", "luv", graph, ram);
addSon("fname", "kush", graph, ram);

// bharat's son
addSon("fname", "Daksha", graph, bharat);
addSon("fname", "Pushkala", graph, bharat);

// laxman's son
addSon("fname", "Angada", graph, laxman);
addSon("fname", "Chanderkedu", graph, laxman);

// Shatrugna's son
addSon("fname", "Shatrugadi", graph,
shatrugna);
addSon("fname", "Subahu", graph, shatrugna);
