Create a class called Name as:

Name
- lastName: String
- firstName: String
+Name(String lastName, String firstName)
+ getLastName(): String
+ setLastName(String lastName): void
+ getFirstName(): String
+ setFirstName(String firstName): void

Write a program with the following requirements:
Creates 10 Name objects with:
? FirstName, LastName are produced randomly from [Oscar, Grouch, John, Lennon, Groucho, Marx, Karl, Marx].
? Ensure that there is no duplicate Name object.
Displays all full name (Name.LastName + Name.FirstName) in ascending order of lastName ( if equals lastName then sort by firstName).

Hint:
• class Name implements Comparable to ordering 2 Name objects.
• override equals(..) method to compare 2 Name objects.
• override toString() method to return full name.
• use Set to ensure no duplicate.
• use Random class to create random value.
• use support class Collections to sort all Name objects.
