2.3. Third Exercise Create a Point class (or change the corrected version from Exercise 01) with two private properties representing x and y coordinates, each of which defaults to the constants originx and originY, which are both initialised to 0. Provide three overloaded constructors: the first one sets the coordinates to their default values; the second gets the coordinates x and y as parameters; and the third receives an object of type Point and transfers its coordinates to the current (this) Point object. Provide a function toString() { [native code] } function that returns a String containing the point coordinates; an example of the delivered result is as follows: (5.1.3, 2.3) Create a PointTest class to put the various constructors and function toString() { [native code] } function to the test.

2.3. Third Exercise
Create a Point class (or change the corrected version from Exercise 01) with two private properties representing x and y coordinates, each of which defaults to the constants originx and originY, which are both initialised to 0.
Provide three overloaded constructors: the first one sets the coordinates to their default values; the second gets the coordinates x and y as parameters; and the third receives an object of type Point and transfers its coordinates to the current (this) Point object.
Provide a function toString() { [native code] } function that returns a String containing the point coordinates; an example of the delivered result is as follows:
(5.1.3, 2.3)
Create a PointTest class to put the various constructors and function toString() { [native code] } function to the test.
