How i use AND operator in sparql querys in java -


I'm learning how to create SPARQL queries in Java. Can anyone tell me how I can experiment in 2 or more questions?

For example: 

  string query string = "select * where {" + "? A

  SELECT * WHERE {? A & lt; http: //dbpedia.org/ontology/capital> ? B? B.RDF: Type & lt; http: //dbpedia.org/ontology/big_city> . }
