Create a Person class that has the properties: name and age. Override toString so that it displays a Person object like this: Where name is the value of the name property and age is the value of the age property. "<Name: name, Age: age>" Person class should have a natural ordering by age in descending order. Create a Main.java file that: Sorts a List of people using Person’s natural ordering. Uses a custom Comparator with an anonymous class that sorts the List of people by name in ascending order. Uses a custom Comparator with a lambda implementation that sorts the list of people by name in descending order.
