Java Math random zero or one generate for guessing head or tail

Question

We would like to write a program that lets the user guess whether the flip of a coin results in heads or tails.

The program randomly generates an integer 0 or 1, which represents head or tail.

The program prompts the user to enter a guess and reports whether the guess is correct or incorrect. 

import java.util.Scanner;

public class Main {
  public static void main(String[] args) {
    Scanner input = new Scanner(System.in);

    //your code here
  }
}



import java.util.Scanner;

public class Main {
  public static void main(String[] args) {
    Scanner input = new Scanner(System.in);

    // Generate a random integer 0 or 1
    int coin = (int)(Math.random() * 2);

    // Prompt the user to enter a guess
    System.out.print("Enter a guess 0-head or 1-tail: ");
    int guess = input.nextInt();

    // Display result
    System.out.println(((guess == coin) ? "Correct" : "Incorrect") + " guess."); 
  }
}
