Imagine that you have access to a class named mycircle that has void setradius(double r) and double getradius() methods. write a static method that accepts a mycircle array. the method should accomplish two goals: it should return the average of the radius’s for all mycircles that have a positive radius, and for any mycircles that have a negative radius it should set the radius to 0.

Code for the method described in the question in java:

public static double averageRadius(MyCircle[] myCircles) {

       double sum = 0;

       for (MyCircle myCircle: myCircles) {

           if(myCircle.getRadius() < 0) myCircle.setRadius(0);

           sum += myCircle.getRadius();

       }

       return sum / myCircles.length;

   }

And the complete program:

import java.util.Random;

public class MyCircle {

   private double radius;

   public double getRadius() {

       return radius;

   }

   public void setRadius(double radius) {

       this.radius = radius;

   }

   public static double averageRadius(MyCircle[] myCircles) {

       double sum = 0;

       for (MyCircle myCircle: myCircles) {

           if(myCircle.getRadius() < 0) myCircle.setRadius(0);

           sum += myCircle.getRadius();

       }

       return sum / myCircles.length;

   }

   public static void main(String[] args) {

       Random random = new Random();

       int N = 10;

       MyCircle[] myCircles = new MyCircle[N];

       for (int i = 0; i < myCircles.length; i++) {

           myCircles[i] = new MyCircle();

           myCircles[i].setRadius(random.nextInt(100));

           System.out.printf("Created MyCircle %d with radius %.2f \n", i, myCircles[i].getRadius());

       }

       System.out.printf("\nAverage radius of %d circles is %.2f \n", N, MyCircle.averageRadius(myCircles));

   }

}

The output was:

Created MyCircle 0 with radius 76.00

Created MyCircle 1 with radius 86.00

Created MyCircle 2 with radius 38.00

Created MyCircle 3 with radius 4.00

Created MyCircle 4 with radius 8.00

Created MyCircle 5 with radius 39.00

Created MyCircle 6 with radius 77.00

Created MyCircle 7 with radius 78.00

Created MyCircle 8 with radius 39.00

Created MyCircle 9 with radius 46.00

Average radius of 10 circles is 49.10

the answer to your question would be something called hertz. the unit of measurement called a hertz, which is one cycle per second, is used to measure clock speed. within one cycle, your computer processes, refreshes, or updates itself to the changes that it is going through. in the case of computer clock speed, one hertz equals one tick per second. the clock speed of computers is usually measured in megahertz (mhz) or gigahertz (ghz)
