Programming Basics Exam - 7 May 2017 , Задача 3. Ученически лагер

Здравейте на всички, моля за малко помощ по конкретната задача. Задачата ми мина в Джъджа 90/100 , но като цяло хич не си харесвам кода и знам, че има и по-лесен начин за решение на задачата. Ако може за насоки и за решението да си го разцъкам и аз.

Ето и моя код:

import java.util.Scanner;

/**

public class SchoolCamp {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);

        String season = scanner.nextLine();
        String group = scanner.nextLine();
        int students = Integer.parseInt(scanner.nextLine());
        int nights = Integer.parseInt(scanner.nextLine());


        if (season.equals("Spring") && group.equals("girls")){
            System.out.print("Athletics ");
            double nightsPrice = students * nights * 7.20;
            if (students >= 50){
                nightsPrice = nightsPrice - (nightsPrice * 0.50);
            }else if (students >= 20 && students < 50) {
                nightsPrice = nightsPrice - (nightsPrice * 0.15);
                System.out.printf("%.2f lv.",nightsPrice);
            }else if (students >= 10 && students < 20){
                nightsPrice = nightsPrice - (nightsPrice * 0.05);
                System.out.printf("%.2f lv.",nightsPrice);
            }else {

    }
}

Не изглежда много добре ...

Аз я реших като написах if-esle if за сезоните, вложен if-else if(и switch става) за вида група(момчета, момичета, смесена), където си определих спорта и цените. Написах формулата за цената на лагера. След това if-else if за бройката и отстъпките и накрая печат.

Не е хубав кода, особено това, че на всеки иф елс изкарваш в конзолата. по-добре да оставиш изхода отделно най-отдолу .

проблема е някъде 20-ти ред;

if (season.equals("Spring") && group.equals("girls")){
            System.out.print("Athletics ");
            double nightsPrice = students * nights * 7.20;
            if (students >= 50){
                nightsPrice = nightsPrice - (nightsPrice * 0.50);
                 System.out.printf("%.2f lv.",nightsPrice);   <------ това липсваше.

Сметнал си го, но не си написал да го изкара на конзолата.

Приятен ден.
