---Write a method in the Store class called averageCustomerAge() which should return an int representing the average age of all Customer objects in the store. Test your code by appending the following line to the end of the StoreTestProgram:. You should get a result of 26. // Find average Customer age  System.out.println(" Average age of customers: " + walmart.averageCustomerAge()); --- Write a method in the Store class called mostPopularGender() which should return a char representing the most popular gender of all Customer objects in the store (i.e., 'M' or 'F'). Test your code by appending the following lines to the end of the StoreTestProgram. The answer should be M. // Find most popular gender  System.out.println(" Most popular gender is: " + walmart.mostPopularGender()); ---Write a method in the Store class called richestCustomer() which should return a Customer object representing the Customer in the store who has the most money. Make sure to return the whole Customer object, not just the name. Test your code by appending the following lines to the end of the StoreTestProgram. The result should be Lore who has $1000: // Find richest customer  System.out.println(" Richest customer is: " + walmart.richestCustomer()); 

Write the following two methods in the Store class. public void changeGender(Customer c) { if (c.gender == 'M') c.gender = 'F'; else  c.gender = 'M'; } public void rob(Customer c) { c.money = 0; } Then test your code by appending the following lines to the end of the StoreTestProgram: // Change Zack's gender while he is shopping at the Store  walmart.changeGender(walmart.customers[25]); System.out.println(" Zack is now: " + walmart.customers[25].gender); // Continue to make Zack's walmart experience quite miserable  walmart.rob(walmart.customers[25]); System.out.println(" Zack is now: " + walmart.customers[25]);
