public class CreatingCollection {
   public static void main( String args[] ) {
      // Creating a Mongo client
      MongoClient mongo = new MongoClient( "localhost" , 27017 );
      // Creating Credentials
      MongoCredential credential;
      credential = MongoCredential.createCredential("sampleUser", "myDb", "password".toCharArray());
      System.out.println("Connected to the database successfully");
      //Accessing the database
      MongoDatabase database = mongo.getDatabase("myDb");
      //Creating a collection
      database.createCollection("sampleCollection");
      System.out.println("Collection created successfully");
   }
}
