All language subtitles for 10. Linked Lists Challenge #1

Okay, the first challenge in this section
2

is to implement the addBefore method
3

for the EmployeeDoublyLinkedList class.
4

This method will take two employees.
5

The first employee will be the employee
6

you want to add to the list
7

and the second employee will be
8

an existing employee in the list
9

and what the addBefore method will do is
10

it will insert the new employee into the list
11

right before the existing employee.
12

So if you call addBefore and you pass
13

James Bond as the new employee,
14

and John Doe as the existing employee
15

then what this method should do is insert James Bond
16

right before John Doe, in the list.
17

Now there's a starter project in the Resources section
18

that you can use.
19

It has all the code you need.
20

So it has the code for the LinkedList,
21

it's the same LinkedList that we implemented
22

when we implemented the DoublyLinkedList
23

and it also has an empty addBefore method
24

inside the EmployeeDoublyLinkedList class.
25

And if you look at the main method
26

in the main.Java file, you'll see that there's code there
27

and that code should work when you're finished.
28

So once you've implemented the addBefore method,
29

run the main method and you should see
30

the new employee added before
31

the employee that you specified.
32

So good luck with this challenge
33

and I'll see you in the solution video.
