我有错误执行Cypher查询在java（嵌入式模式）这是我的代码：

    import org.neo4j.cypher.internal.ExecutionEngine;
    import org.neo4j.cypher.internal.ExecutionResult;
    import org.neo4j.graphdb.GraphDatabaseService;
    import org.neo4j.graphdb.factory.GraphDatabaseFactory;
    public class test {
    public static void main(String[] args) {
    GraphDatabaseFactory graphdbFactory = new GraphDatabaseFactory();
    GraphDatabaseService graphdb = new graphdbFactory.newEmbeddedDatabase("C:/Users/dell/Documents/Neo4j");    
    ExecutionEngine execEngine = new ExecutionEngine(graphDb);
    ExecutionResult execResult = execEngine.execute
               ("MATCH (java:JAVA) RETURN java");
    String results = execResult.dumpToString();
    System.out.println(results);
}

}

我在该行收到错误：GraphDatabase aseService graph db=new graph dbFactory. newEmbeddedDatabase（"C：/User/dell/Documents/Neo4j"）；错误：类型图数据库工厂中的新嵌入式数据库（文件）方法不适用于参数（字符串）

请帮忙
