Please solve this in JAVA. Ps: This is not the exacy same program as previous one where it has an enum SIGNUM it's similar but not same this one is only enum Quadrant so please solve this according to the question and not just copy paste from the old problems. Quadrant (the code):
public enum Quadrant {
// code
}
We will model the four quadrants with a Java enumeration which will contain only 4 elements and a few methods. The enumeration will have a main() method that takes command line arguments that are pairs of numbers and prints which quadrant the pair belongs to.
Note that there is some ambiguity as to which quadrant pairs with a 0 belong in: the pair (0, 11) exists on the boundary between Q1 and Q2 while the origin (0,0) could be said to belong to any of the quadrants. We will dodge that issue by not testing such cases so your code may behave any way you wish.
Fields & Methods:
Q1, Q2, Q3, Q4
There are four elements of the Quadrant enumeration: Q1, Q2, Q3, Q4. Ensure that these are all present and no other exist.
public boolean xPositive();
public boolean yPositive();
These two simple accessors indicate whether the coordinates of the Quadrant are positive or negative. In order to make this functionality easy, it is helpful to define some private fields and a private constructor.
public String signPair()
Quadrants can return a pretty string which indicates the sign of the x and y values they contain. These are the strings
(+,+) for Q1
(-,+) for Q2
(-,-) for Q3
(+,-) for Q4
public Quadrant flipX();
For a coordinate (x, y) in this Quadrant, method flipX() should return the Quadrant that would the coordinate (-x, y) would belong to.
public static Quadrant fromInts(int x, int y)
This function returns the Quadrant in which the pair (x, y) would fall. As noted earlier, if x or y are 0, multiple quadrants apply. Return any valid choice in such cases but know that this case will not be tested in the test cases.
Example
From an interactive session in DrJava
Welcome to DrJava.
> Quadrant q = Quadrant. fromInts(1,4);
> q
Q1
> q = Quadrant. fromInts(11,-34);
> q
