To retrieve data from MongoDB using Java, you can use a library called MongoDB Java Driver. Here's a basic example of how to connect and find documents:

```java
import com.mongodb.*;

MongoClient mongoClient = new MongoClient("localhost", 27017);
DB db = mongoClient.getDB("test"); // Your database name
DBCollection collection = db.getCollection("users"); // Your collection name
DBCursor cursor = collection.find();
while (cursor.hasNext()) {
System.out.println(cursor.next());
}
```
