what is this for?

Question about the task

Resolved

is there any way to explain what kind of problem this solves?

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 second quadrant: a<0 and b>0;
for the third quadrant: a<0 and b<0;
for the fourth quadrant: a>0 and b<0.

Example for 4 6:
1
Example for -6 -6:
3

Requirements:

The program should read the numbers from the keyboard.
The program should use System.out.println() or System.out.print().
If the point is in the first quadrant, display "1".
If the point is in the second quadrant, display "2".
If the point is in the third quadrant, display "3".
If the point is in the fourth quadrant, display "4".

I'm not a programmer yet to be able to say for sure what programming area it has to do with. I have some ideas, though. For example, defining a position or a direction relative to a given starting point. For example, for some kind of graphics. Or if you are looking for some data in a two-dimensional array; etc. Thinking in such coordinate systems can be necessary in a lot of cases, I think. In general, these tasks are designed to develop thinking skills.

Cartesian coordinates are used everywhere. To start its a mathematical concept used in algorithms for: - Graphic design - travel/GPS/Mapping - data collection/mining - science - word processing - friend suggestions on sites like Facebook - Google searches - etc.
