Chapter 9.10, Problem 9.10.2CP

Show the output of the following program:

public class Test {

publ1c static void main(String[] args)

Circle circle1 =new Circle (1);

Circle circle2 =new Circle (2);

swap1(circle1, circle2);

System.out.println("After swap1: circle1 =" + circle1.radius+ " circle2 = " + circle2.radius);

swap2(circle1 , circle2);

System.out.println("After swap2 : circle1 = " + circle1.radius+ "circle2 =" + circle2.radius);

}

public static void swap1(Circle x, Circle y) {

Circle temp= x;

X = y;

y = temp;

public static void swap2(Circle x, Circle y) {

double temp = x.radius;

x.radius = y.radius;

y.radius = temp;

}

}

class Circle {

double radius;

Circle(double newRadius)

radius = newRadius;

}

}
