I am trying to connect to databricks using java code. Can someone help me please? Here is the code so far I have got::

  
import java.sql.Connection; 
import java.sql.DriverManager; 
import java.sql.SQLException; 
import java.util.Properties;
 
  
  public class DatabricksSetup {
       
    public static void main(String[] args) throws SQLException {
 
      String url = "jdbc:databricks://XXXX.azuredatabricks.net:443/default;transportMode=http;ssl=1;httpPath=sql/protocolv1/o/XXXXX;AuthMech=3;UID=token;PWD=XXXXXX";
 
       String username = "token";
       String password = "XXXX"; //Token generated from databricks profile page.
       Connection connection = DriverManager.getConnection(url, username, password);
    
       System.out.println("Database connected!");
 
       if(connection != null){
         System.out.println("Connection Established");
        }
       else {
         System.out.println("Connection Failed");
 
      }  
 
    }
 
  }

@Dipak Bachhav do you have any restriction in terms if IP to access databricks, in case of that you need to enable particular ip from security groups
