Coin Progam Help

Question

I need help writing a program that simulates the flipping of a coin 1000 times to see how often heads or tails come up. So far I have this:
import java.util.Random; //allows us to use random
     public class CoinClass
         //instance variables
           private int coin;
           private int heads=0;
           private int tails=1;
          //constructors
             public CoinClass()
          flip();
            // methods
          public int flip()
            face = (int)(Math.random()*2) + 1;
            public boolean heads()
             {      return(face==heads) 
           public boolean tails()
             {      return(face==tails) 
          public String toString()
           String faceName;
           if (face == heads)
         faceName = "Heads";
           else
         faceName = "Tails";
           return faceName;
     and
     public class CoinClassMain
          public static void main(String[] args)
         int numHeads=0;
         int numTails=0;
         int numFlips=0;
         int face;                              //keeps track of number of snake eyes
         CoinClassMain coin = new CoinClassMain();
              for(int i=0; i<=1000;i++)
                     coin.flip();
                       numFlips++;
     }But now I am at a lost as to what to do?
Any help would be appreciated!

Not quite sure I agree with prometheuzz about the counters, I think you've got them just right; but his constants for HEADS and TAILS are spot on. You can even make them public. Also, the "face" isn't really part of a coin, it's the result of a flip(), so you could simply have:public int flip() {
   return (int)(Math.random()*2) + 1;
}You also don't really need to do a flip() in your constructor; it's redundant.
Your main class is almost there. Try and think of it this way (a bit of pseudo-code here):
do 1000 times {
flip the coin
check the result
if it's heads {
do required stuff for a head
otherwise {
do required stuff for a tail
}
