1. 
   To’rt o'zgaruvchiga ega bo'lgan sinf yarating. Displey funktsiyasini va ushbu o'zgaruvchilarni o'zgartirish funksiyasini qo'shing. Ushbu o'zgaruvchilar qiymatlari yig'indisini topadigan va shu to’rt o'zgaruvchining eng katta qiymatini topadigan funksiyani qo'shing.

2. 
   Belgilangan diapazonda qiymatini bittaga oshirishi yoki kamaytirishi mumkin bo'lgan o'nli hisoblagichni amalga oshiradigan sinfni tavsiflang. Standart qiymatlar va ixtiyoriy qiymatlar bilan hisoblagichni ishga tushirishni ta'minlang. Hisoblagich ikkita usulga ega bo’lishi kerak:
   

• 
  oshirish va kamaytirish;
  
• 
  hozirgi holatini olishga imkon berish.
