How to take over the world
Enter a name and number from the keyboard, and then display the line: «name» will take over the world in «number» years. Mwa-ha-ha!
Example: Kevin will take over the world in 8 years. Mwa-ha-ha!
The order in which the data is input matters a lot.

Why on earth do the print instructions use buffered reader, but the video only addresses scanner? That combined with the lack of solid instruction in this section makes these exercises a little undirected and confusing.

In the Level2, Lesson 7 :
Example 3: In which we've used Scanner scanner = new Scanner(System.in);
But in all the excercises in next lesson, when I try this method, it produces error. So, I have to unwillingly use more complex methods. Can I import java.util.Scanner in the code environment provided by you
I agree with everyone who is saying this section is a little tougher and not as well explained. I also am using this as reinforcement for my current Java class. I wonder why they default to BufferedReader, my Java class defaults to using the Scanner.
With all due respect shouldn't we get intro to classes/objects before using/creating them in practice? It feels like there was a lot of theory skipped in those tasks. The explanation regarding Input creation, different possibilities I get a feeling was written on a knee and is not even nearly enough to grasp the understanding. Unless this course teaches "programming" as copy & paste of the code which people don't understand?
