dbconnection = mongo.getDatabase(“school”); This is database name

collection= dbconnection.getCollection(“records”); This is a table name

    MongoClient mongo;
    MongoDatabase dbconnection;
    MongoCollection<org.bson.Document>  collection;
   
    public void Connect()
    {    
        mongo = new MongoClient("localhost",27017);
        dbconnection = mongo.getDatabase("school");

after done the connet() method call inside the constructor of the class

   public Registation() {
        initComponents();
        Connect();
    }

Paste the Code Inside the Find Button

BasicDBObject search = new BasicDBObject();
search.put("name", txtName.getText());
MongoCursor<Document> cursor = collection.find(search).iterator();
     while (cursor.hasNext()) 
        {
            System.out.println(cursor.next()); 
        }
