DB db = DB.open(options, new File("example"));
try {
  // Use the db in here....
} finally {
  // Make sure you delete the db to shutdown the 
  // database and avoid resource leaks.
  db.delete();
}

WriteOptions wo = new WriteOptions();
ReadOptions ro = new ReadOptions();

db.put(wo, bytes("Tampa"), bytes("rocks"));
String value = asString(db.get(ro, bytes("Tampa")));
db.delete(wo, bytes("Tampa"));
