Flip a coin (Assignment)

How many times in a row can you flip a coin and gets heads?

Use the random number generator to simulate the flipping of the coin. 0 means heads, 1 means tails.

Start a loop,

flip it, if heads, count it and keep flipping.

If tails, stop the loop.

Display the number of times in a row that heads came up.

Once this is working, wrap a while loop around the loop that flips the coin to play again if the user says they want to.

Run and test this loop.

Sample Output: You flipped the coin and got HEADS 0 times in a row!

Want to try again? (Y or N) Y

You flipped the coin and got HEADS 3 times in a row!

Want to try again? (Y or N) N

Thank you for playing. Have a good day.

Code

import java.util.Scanner;
public class Flip {

  public static void main(String[] args) 
  {
     Scanner in = new Scanner(System.in);
     while(true) //loop till enters N
     {
       int c=0;
       while(true) //loop till tail flipped
       {
         int r=(int)(Math.random() * 2);
         if(r==0)
         {
           c++;
         }
         else
         {
           break;
         }
       }
       System.out.println("You flipped the coin and got HEADS "+c+" times in a row!");
       System.out.print("Want to try again? (Y or N) ");
       char ch=in.next().charAt(0);
       if(ch=='N')
       {
         System.out.println("Thank you for playing. Have a good day.");
         break;
       }
     }
  }

}
