Write a program that simulates flipping a coin to make decisions. The input is how many decisions are needed, and the output is
Travka [436]

Answer:

Here is the JAVA program:

import java.util.Scanner;  // to get input from user

import java.util.Random;   // to generate random numbers

public class CoinFlip {  

// function for flipping a coin to make decisions

  public static String HeadsOrTails(Random rand) {

//function to return head or tail

     String flip;   // string type variable flip to return one of the heads or tails

     if ((rand.nextInt() % 2) == 0)  

// if next random generated value's mod with 2 is equal to 0

        {flip = "heads";}  // sets the value of flip to heads

     else   // when the IF condition is false

       { flip = "tails";}   // sets value of flip to tails

  return flip;    }    //return the value of flip which is one of either heads or tails

  public static void main(String[] args) {  //start of main function body

     Scanner rand= new Scanner(System.in);  // creates Scanner instance

// creates random object and seeds the program with value of 2

     Random no_gen = new Random(2);  

     int decision = rand.nextInt();   //calls nextInt() to take number of decisions

     for (int i = 0; i < decision; i++) {

// produces heads or tails output for the number of decisions needed

        System.out.println(HeadsOrTails(no_gen));       }    }    }

//prints heads or tails

Explanation:

The above program has method HeadsOrTails(Random rand) to return the heads or tails based on the condition if ((rand.nextInt() % 2) == 0) . Here nextInt() is obtains next random number from the sequence of random number generator and take the modulus of that integer value with 2. If the result of modulus is 0 then the value of flip is set to heads otherwise tails.

In the main() function, a random object is created and unique seed 2 is set. The decision variable gets the number of decisions. In the for loop the loop variable i is initialized to 0. The loop body continues to execute until the value of i exceeds the number of decisions needed. The loop body calls the HeadsOrTails(Random rand) method in order to output either heads or tails.

The program and output is attached in a screenshot.
