MongoDB list available databases in java

Question

I am writing an algorithm that will go thru all available Mongo databases in java.

On the windows shell I just do

show dbs

How can I do that in java and get back a list of all the available databases?

Answer 1

You would do this like so:

MongoClient mongoClient = new MongoClient();
List<String> dbs = mongoClient.getDatabaseNames();

That will simply give you a list of all of the database names available.

You can see the documentation here.

Update:

As @CydrickT mentioned below, getDatabaseNames is already deprecated, so we need switch to:

MongoClient mongoClient = new MongoClient();
MongoCursor<String> dbsCursor = mongoClient.listDatabaseNames().iterator();
while(dbsCursor.hasNext()) {
    System.out.println(dbsCursor.next());
}
