Можно через switch написать, будет удобнее читать

rub ="рублей";
}else if((formatedAmount % 10) == 1) {
rub ="рубль";
}else if((formatedAmount % 10 > 1) && (formatedAmount % 10 <= 4)) {
rub ="рубля";
}else{
rub ="рублей";
}

return rub;
}

class Product {
public String name;

public Product(String name, double price) {
this.name = name;
this.price = price;
}
