Quadrants
Use the keyboard to enter two integers representing the coordinates of a point not on the X and Y axes.
Display the number of the quadrant that contains the given point.
Hint:
Point (a, b) belongs to a quadrant if the following conditions are true:
for the first quadrant: a>0 and b>0;
for the
change the import for :
import java.io.BufferedReader;
import java.io.InputStream; // Ajout de l'import nécessaire
import java.io.InputStreamReader;
import java.io.Reader;
Or else it can't work
I have to agree, the assignment should reflect what you concentrated on in the lesson. If we are going to use Bufferedreader that us what should be concentrated on ib the lesson.
why can't just use scanner(easier) any ways... learned about this buffer reader. Thanks.

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.
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?
