ChodeHS Exercise 4.3.5: Coin Flips Write a program to simulate flipping 100 coins. Print out the result of every flip (either Heads or Tails).

At the end of the program, print out how many heads you flipped, how many tails you flipped, what percentage were heads, and what percentage were tails.

public class CoinFlips extends ConsoleProgram

{

   public static final int FLIPS = 100;

   public void run()

   {

       int countH = 0;

       int countT = 0;

       for(int i = 0; i < 100; i++)

       {

           if (Randomizer.nextBoolean())

           {

               System.out.println("Heads");

               countH += 1;

           }

           else

           {

               System.out.println("Tails");

               countT += 1;

           }

       }

       System.out.println("Heads: " + countH);

       System.out.println("Tails: " + countT);

       System.out.println("% Heads: " + (double) countH / FLIPS);

       System.out.println("% Tails: " + (double) countT / FLIPS);

   }

}

Explanation:

First define your counting variables for both heads and tails (I named them countH and countT). Set them to 0 at the start of the run.

Then use a for loop to flip the coin 100 times. In the video you should have learned about the Randomizer class so you can use the same idea to print out whether you got heads or tails.

Make sure to keep the count going using >variable name< += 1.

The printing at the end is very basic; print the statement for each: ("Heads: " + >variable name<);

For the percentages, print ("% Heads: " + (double) >variable name< / FLIPS); divided by FLIPS (not 100 or any other int because you will get the wrong value) and remember to cast them as doubles to get the correct value.
