Question

java language question:

Write a thread that tosses a coin 1000 times and computes the frequency of heads and tails. A coin can be modelled by a random number generator that generates random numbers in the range 0..1.

Answer 1

import java.util.Random;

//class coinToss
class coinToss extends Thread
{
public void run()
{
//variable declaration and initialization
int toss, tail=0, head=0;
Random rand = new Random();
  
for(int i=0; i<1000; i++)
{
//assign random number 0 or 1
toss = rand.nextInt(2);
//we assume that if random number is 1 then it is head otherwise tail
if(toss == 1)
{
head++;
}
else
{
tail++;
}
}
//display the frequency of head
System.out.println("Frequency of heads: " + head);
//display the frequency of tail
System.out.println("Frequency of tails: " + tail);
}
}

//main class
public class Main
{
   public static void main(String[] args)
   {
       coinToss toss = new coinToss();
       //method calling
toss.start();
   }
}

OUTPUT:
