write code defining a method named swap(Point p) that will change the x and y coordinates...

write code defining a method named swap(Point p) that will change the x and y coordinates for any Point object passed to it. So a call to swap(p) where p has x=3 and y=50 resets the point with x=50 and y=3. A call to swap(q) changes the coordinates of point q from x=88,y=25 to x=25, y=88

Write a class called Point that contains two doubles that represent its x- and y-coordinates. It should have get and set methods for both fields. It should have a constructor that takes two double parameters and initializes its coordinates with those values. It should have a default constructor that initializes both coordinates to zero. It should also contain a method called distanceTo that takes as a parameter another Point and returns the distance from the Point that was passed as...

Write a method named factorial that accepts an integer n as a parameter and returns the factorial of n, or n!. A factorial of an integer is defined as the product of all integers from 1 through that integer inclusive. For example, the call of factorial(4) should return 1 2 3 4, or 24. The factorial of 0 and 1 are defined to be 1. You may assume that the value passed is non-negative and that its factorial can fit...
