Question

James is holding his annual coin flipping contest, and to prepare for it he would like you to help him practice. Write James a program that asks the user how many times he would like his coin to flip (he can flip up to 1000 times). Then randomly generate a number between 1 and ten, store all the numbers in an array. With your newly created array, supply James with the following information:

- How many times each number out of 10 showed up.

-What number showed up the most.

- If even numbers are heads, and odd numbers are tails, what side of the coin came up the most?

Please ensure that the program is well commented.

***Also- Add another input for James Asking him how many times he would like to perform his run through the flips (example, 3 flips of 30, 2 flips of 100) your output will now have a comparison between each trial. Try to incorporate as many arrays as possible!!! Submit a README.txt file

p.s. I am using java 1.4.2 and I cannot use any newer. I cannot use classes like scanner and such. Please ensure that the program works with 1.4.2 an not any newer. Thank you

Explanation / Answer

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.util.Random;

public class CoinFlips
{
   public static void main(String[] args) throws NumberFormatException, IOException
   {
       //Maximum flips
       final int MAX_FLIPS = 1000;
       InputStreamReader inp=new InputStreamReader(System.in);
       BufferedReader input=new BufferedReader(inp);
       int nUserFlips = 0;
      
       //Reading user input until he enters a valid input
       while(true)
       {
           System.out.println("Enter no of Flips(<1000) :" );
           nUserFlips = Integer.parseInt(input.readLine());
           //Check whether the input values exceeding the max allowed flips or not
           //If yes, throw an error and ask the user to qnother value
           if(nUserFlips > MAX_FLIPS)
               System.out.println("Error : No of flips should be less than "+MAX_FLIPS+".");
           else
               break;
       }
       Random rand = new Random();//Random class for generating the Random Numbers
       //Random numbers should be in [1,10]
       int min = 1, max = 10;
       //Array for storing coin flip values
       int[] flips = new int[nUserFlips];
       //Frequency count for 1...10 numbers
       int[] freq = new int[10];
       int nEvenCount = 0, nOddCount = 0;
       //loop for generating Number and count even number and odd numbers
       for(int i=0;i<nUserFlips;i++)
       {
           rand = new Random();
           flips[i] = min + rand.nextInt(max-min);
          
           if(flips[i]%2 == 0)
               nEvenCount++;//Even numbers
           else
               nOddCount++;//Odd Numbers
       }
       //Loop for calculating frequency
       for(int i=1;i<=10;i++)
       {
           int temp = 0;//Initial Frequency count for each number
           //Loop through the flips and count frequency for each number
           for(int j=0;j<nUserFlips;j++)
           {
               if(flips[j] == i)
                   temp++;
           }
           freq[i-1] = temp;//Inserting freq to an array
           System.out.println("The number "+i+" showed up "+temp+" Time(s).");
       }
      
       //Finding out the number with max occuring frequency
       int biggestCount = 1;
       int biggest = freq[0];
       for(int i=1;i<10;i++)
       {
           if(biggest < freq[i])
           {
               biggest = freq[i];
               biggestCount = (i+1);
           }
       }
       System.out.println("number "+biggestCount+" showed up the most.");
       if(nEvenCount > nOddCount)
       {
           System.out.println("heads came up the more");
       }
       else if(nEvenCount > nOddCount)
       {
           System.out.println("tails came up the more");
       }
       else
       {
           System.out.println("Both heads and tails came up the same no of times");
       }      
   }
}

Got confused a little with this text so i haven;t done anything related to this part, ***Also- Add another input for James Asking him how many times he would like to perform his run through the flips (example, 3 flips of 30, 2 flips of 100) your output will now have a comparison between each trial.

Check and let me know, if i need to add something to the program.
