Explanation:
- In the above program, the “Point” is the class name,
- Inside the “Point” class, declare the “x” and “y” variables and the accessor method, the “quadrant” is the method name
- If the “x” and “y” are greater than 0, then return 1 to the called method.
- If the “x” is less than 0 and “y” is greater than 0, then return 2 to the called method.
- If the “x” and “y” are less than 0, then return 3 to the called method.
- If the “x” is greater than 0 and “y” is less than 0, then return 4 to the called method.
