Simplest Ticket Component

public class SimpleTicketPriceComponent {public String priceRequest(String airportCode) throws Exception{

if(airportCode.equals("SFO")){

return "300";}else if (airportCode.equals("MLT")){

return "1300";}else if(airportCode.equals("HEL")){

return "300";}else{

return "Unknown code "+airportCode;

}}

}

What about using a Map instead of static values?

What about making the component configurable through Spring?

Practical Lab

Take input from console in the form of airport code:– MLT, SFO, HEL

Display the price of the ticket to screen:– 300,400

Must create POJO and use it as a component in the configuration

Optional:– Make POJO configurable through configuration

– Configure STDIO connector to have a more

user friendly application
