Question

Write a program called CountFlips whose main method flips a coin 100 times and counts how many times each side comes up. Make sure to include comments of what is being done in the code. Verify whether the head comes up or not by calling isHeads method of Coin class. Increment the heads count if head comes up. Increment the tails count if tail comes up. Display the head and tails counts.

Print the results SEND AS A TEXT FILE USING JAVA ECLIPSE AND MAKE SURE IT IS SENT IN THE EXACT FORM AS I WILL BE COPYING AND PASTING IT INTO JAVA ECLIPSE, MAKE SURE TO STATE WHAT IS BEING DONE IN THE CODE. WILL GIVE A THUMBS UP.

Answer 1

import java.util.Random;

class Coin {
   private String sideUp;

   public Coin() {
       toss();
   }

   public void toss() {
       // generating random number, if it even return Heads else Tails
       if (new Random().nextInt(2) == 0)
           sideUp = "heads";
       else
           sideUp = "tails";
   }

   public String getSideUp() {
       return sideUp;
   }

}

public class CountFlips {
   public static void main(String[] args) {
       int headCount = 0, tailCount = 0;
       Coin cf = new Coin();
       //iterating 100 times
       for (int i = 0; i < 100; i++) {
           //tossing the coin
           cf.toss();
           //checking the side
           // increase count based on side
           if (cf.getSideUp().equals("heads"))
               headCount++;
           else
               tailCount++;
       }
       System.out.println("Tails count: " + tailCount);
       System.out.println("Heads count: " + headCount);

   }
}
