    Default 'local variable hides a field'

    I'm getting this error when trying to set the value of an int to a specific user input with the scanner. here's my code:

    package coinflip;
     
    import java.util.Scanner;
     
    public class CoinFlip
    {
         public int userinput;
       //-----------------------------------------------------------------
       //  Creates first coin object, and flips it. 
       //-----------------------------------------------------------------
       public void main (String[] args)
       {
               Scanner scan = new Scanner(System.in);
               System.out.println("Enter the desired number of flips.");
               int userinput = scan.nextInt();
     
                   }
       {
          Coin c1 = new Coin();
     
         c1.flip();
          c1. getvalue();
          System.out.println(c1.getvalue());
     
     
          Coin c2 = new Coin();
          c2.getvalue();
          System.out.println(c2.getvalue());
     
          if (c1.getvalue() > c2.getvalue()) {
          System.out.println ("Tails! Player 2 Wins!");
          }
          else if (c1.getvalue() < c2.getvalue()) {
              System.out.println("Heads! Player 1 Wins");
          }
         else if (c1.getvalue() == c2.getvalue()) {
              System.out.println("Tie!");
     
     
       }
          }
     
     
    }

    //********************************************************************
    //  Coin.java       Author: Lewis/Loftus
    //
    //  Represents a coin with two sides that can be flipped.
    //********************************************************************
     
    package coinflip;
     
    public class Coin
    {
       private final int HEADS = 0;
       private final int TAILS = 1;
     
       private int face; 
       private int p1wins = 0;
       private int p2wins =0;
       private int ties = 0;
     
       //-----------------------------------------------------------------
       //  Sets up the coin by flipping it initially.
       //-----------------------------------------------------------------
       public Coin ()
     
       {
          flip();
       }
     
       public int p1; //increment p1win each time player 1 wins, must be tied into flip
       {
           p1wins++;
       }
       public int p2; //incremnt p2win each time players 1 wins, must be tied into flip
       {
           p2wins++;
       }
       public int tie;
       {
           ties++;
       }
     
       public int getvalue ()
       {
           return face; 
       }
       //-----------------------------------------------------------------
       //  Flips the coin by randomly choosing a face value.
       //-----------------------------------------------------------------
       public void flip ()
       {
          face = (int) (Math.random() * 2);
       }
       {
           System.out.println("Face is: "+ face);
       }
    }

    I also need advice as for how to tell the program to repeat the coinflip a certain number of times. Would this be through a conditional statement? I think it is, but I can;t find one that seems to work.

    At least he mentioned the cross-post in his original post. For that I give him kudos.
