Java Program

The assignment requires two classes. Put all classes in the same package.

Class Employee

Attributes (all private):

id: String
lastName: String
firstName: String
salary: int

Methods:

Parameterized constructor for initializing a new Employee instance
Getters for all attributes
toString method to display an Employee's attributes (See output of executable below)

Executable Class

Create an array of at least eight Employee objects.
Be sure to use many with identical last names, but don't order them by name in the array.
Create an ArrayList from the array.
Sort the ArrayList first by last name and then by first name.
Using the forEach method and a lambda expression, print all employees alphabetically sorted by name.
Create a LinkedList from the ArrayList.
Create an iterator capable of cycling both forward and backward through the LinkedList.
Iterate forward through the LinkedList without generating any output.
Then iterate backwards through the LinkedList to print the employees in reverse alphabetical order.

Example Output
Staff Alpha sorted by names
ID 23232:Baker, Amy, salary $100,000
ID 12345:Baker, Tom, salary $200,000
ID 56789:Jones, Dan, salary $130,000
ID 67765:Jones, Don, salary $140,000
ID 13579:Jones, Pat, salary $80,000
ID 45454:Perez, Ava, salary $105,000
ID 24680:Scott, Ann, salary $90,000
ID 11111:Scott, Bob, salary $65,000
Staff sorted Reverse Alpha
ID 11111:Scott, Bob, salary $65,000
ID 24680:Scott, Ann, salary $90,000
ID 45454:Perez, Ava, salary $105,000
ID 13579:Jones, Pat, salary $80,000
ID 67765:Jones, Don, salary $140,000
ID 56789:Jones, Dan, salary $130,000
