I keep getting this error message:

java.lang.ClassNotFoundException: org.postgresql.Driver:Slankbank

I don't know how to fix this.

import java.sql.Connection;
import java.sql.DriverManager;

public class Test{
    public static void main(String[] args){
        connect();    
    }

    protected static void connect(){
        String hostURL = "jdbc:sqlserver://145.24.222.162:3306/eqod-log";
        String Username = "admin";
        String Password = "Slankbank2020!";
        Connection con = null;

        try {
            Class.forName("org.postgresql.Driver:Slankbank");
            con = DriverManager.getConnection(hostURL, Username, Password);
            System.out.println("connection successful via ip address");
        }
        catch (Exception e) {
            e.printStackTrace();
        }
    }
}

Yes the libraries are imported.
