Chapter 8, Problem 20RE

Explanation of Solution

Swap floating point numbers:

//define a method swap()

public static void swap(Point2D.Double p)

{

//swap the values

p.setLocation(p.getY(), p.getX());

}

//define the main() method

public static void main(String[] args)

{

//declare the floating point values

double x = 3;

double y = 4;

//define the object of Point2D.Double

Point2D.Double p = new Point2D.Double(x, y);

//call the method swap()

swap(p);

//set the value of x

x = p.getX();

//set the value of y

y = p.getY();

//print the values

System.out.println(x + " " + y);

}

Explanation:

The above snippet of code is used to swap floating point values...
