For the Attraction class, we have two variables name and price. Create a defalult constructor and custom constructor for the Attraction class. Write down the getters and setters for the name and price variables. Finally, write a method to print the attraction name and the price. For the TourismBook class, we have an array of attractions and a variable to store the number of attractions. Write down the defalult constructor. Write down a getter method getAttractions() for the attractions. Write down two different methods addAttraction(Attraction c) and addAttraction(String n, double p) to add attractions. Write down a method nameBestAttraction() which selects the attraction having minimum price.
