Question

Write a program to toss a coin multiple times. Ask the user for how many times to toss the coin and then display the percentage of heads and tails (do not display each toss, just the totals). JAVA

Answer 1

JAVA Program:

import java.io.*;
import java.util.*;

class Toss {
   public static void main (String[] args) {
   int count,headcount=0,tailcount=0,toss;
       System.out.print("Enter the number of times to toss the coin: ");
       Scanner sc = new Scanner(System.in);
       count = sc.nextInt();
       Random rand = new Random();
       //0 -- head 1 -- tail
       for(int i=0;i<count;i++){
       toss = rand.nextInt(2);
       if(toss==0)
       headcount++;
       else
       tailcount++;
       }
       System.out.println("Total head count is "+headcount);
       System.out.println("Total tail count is "+tailcount);
       System.out.printf("Percentage of heads is %.2f\n",(float)headcount/(float)count);
       System.out.printf("Percentage of tails is %.2f",(float)tailcount/(float)count);
   }
}

Output:
