if a method returns Object, how to convert to String value?

Question

as below, "n.getNodeData().getAttributes().getValue("sex")" will return a Object value, but how can i match it with String value "male"? so that i can extract out all value in the column who is male?

for (Node n : graphModel.getGraph().getNodes()) {
            if(n.getNodeData().getAttributes().getValue("sex") == "male")
            System.out.println(n.getNodeData().getAttributes().getValue("sex"));
        }

First of all, read [this](http://stackoverflow.com/questions/513832/how-do-i-compare-strings-in-java). Second, implement an appropriate `toString` method and invoke it. — Sotirios Delimanolis, Jun 25 '14 at 21:20
What type does n.getNodeData().getAttributes().getValue("sex") return? If it returns a String, use the equals method to compare with "male" instead of "==" — Vivin, Jun 25 '14 at 22:12
