Point.java starter

//class header for class Point

//instance variables - an int for x and an int for y

//default constructor to set x and y to 0

//specified constructor to initialize specific values for x and y

//accessors/getters for x and y

//mutators/setters for x and y

//toString - returns a String of the format (x, y)

/*Add the following method to the Point class:

public int quadrant()

Returns which quadrant of the x/y plane this Point object falls in. Quadrant 1 contains all points whose x and y values are both positive. Quadrant 2 contains all points with negative x but positive y. Quadrant 3 contains all points with negative x and y values. Quadrant 4 contains all points with positive x but negative y. If the point lies directly on the x and/or y axis, return 0.
*/

/*Add the following method to the Point class:

public void flip()

Negates and swaps the x/y coordinates of the Point object. For example, if the object initially represents the point (5, -3), after a call to flip, the object should represent (3, -5). If the object initially represents the point (4, 17), after a call to flip, the object should represent (-17, -4).
*/

/*Add the following method to your Point class:

public boolean isVertical(Point other)

Returns true if the given Point lines up vertically with this Point; that is, if their x coordinates are the same.
*/

/*Add the following method to the Point class:

public double slope(Point other)

Returns the slope of the line drawn between this Point and the given other Point. Use the formula (y2 - y1) / (x2 - x1) to determine the slope between two points (x1, y1) and (x2, y2). Note that this formula fails for points with identical x-coordinates
