Java & MongoDB - Display Collections
To display list of collections, you can use database.listCollectionNames() method to get the list of collection names in the databases.
MongoIterable<String> collections = database.listCollectionNames();
Example
Following is the code snippet to display list of collections −
import com.mongodb.client.MongoClient; import com.mongodb.client.MongoClients; import com.mongodb.client.MongoDatabase; import com.mongodb.client.MongoIterable; public class Tester { public static void main(String[] args) { // Creating a Mongo client MongoClient mongoClient = MongoClients.create("mongodb://localhost:27017"); // Get the database MongoDatabase database = mongoClient.getDatabase("myDb"); // Create the collection database.createCollection("sampleCollection"); // Get the list of collection names MongoIterable<String> collections = database.listCollectionNames(); for (String name : collections) { System.out.println(name); } } }
Now, let's compile and run the above program as shown below.
$javac Tester.java $java Tester
Output
On executing, the above program gives you the following output.
