Hey,
I'm nearly done.Thanks for all your help...
Now I have only 2 small problems. I need my counters to count separately for each of the different winnings
(tie++,computerWins++ and playerWins++) .
The other thing I need help is for the game application to stay open for the player to play and closes only when they enter an invalid statement--so that's loop too right? I have done the most part, it's just a few lines I guess I am missing that I can't seem to figure out. I have pasted the appropriate class and the driver. Please help...I am nearly done! Are there things I need to change?

My driver:
Code:
import java.io.*;
import rps.*;
public class RockPaperScissorsDr {
  public static void main(String []args) throws IOException
  {

  Player player;
    Decider decider;
    String playerEntry;
    int playerWins=0,computerWins=0,ties=0;
     System.out.println("An invalid entry will close the game!");
     System.out.println("Please choose from the menu, the letter you would like to play");
    BufferedReader in;
   in=new BufferedReader(new InputStreamReader(System.in));
   System.out.print("Enter r for rock,p for paper,s for scissors:");
   playerEntry=in.readLine().toLowerCase();
   System.out.println("Player played is "+playerEntry);
   while(playerEntry!=null){
 int computerChoice=(int)(Math.random()*2+1);
   System.out.println("The computer played "+computerChoice);
   if(!(!playerEntry.equals("r"))&&(!playerEntry.equals("s"))&&(!playerEntry.equals("p"))){
    System.out.println("The winner is: " +Decider.decideWinner(computerChoice,playerEntry));}
   else
    { System.out.println("Player's choice is invalid.The game will close!");}
//System.out.println("To play again,please enter letter from menu: ");
//playerEntry=in.readLine().toLowerCase();
System.out.println("The computer won "+computerWins);
System.out.println("The player won "+playerWins);
System.out.println("There were "+ties+" ties. Thank you for playing");



   }
          }}
My class:
Code:
package rps;
public class Decider {
 public static String decideWinner(int computerChoice,String playerEntry)
  {
    String winner;
    int rock=1;
    int paper=2;
    int  scissors=3;
  if(computerChoice==1&&playerEntry.equals("r")&&computerChoice==2&&playerEntry.equals("p")&&
       computerChoice==3&&playerEntry.equals("s")){
      winner = "draw";


    }
      else if(computerChoice==1&& playerEntry.equals("r"))//rock breaks scissors
      {
        winner="computer";


      }
          else if(computerChoice==3&&playerEntry.equals("p"))//scissors cut paper
          {
            winner ="computer";

          }
          else if(computerChoice==2&&playerEntry.equals("r"))//paper covers rock
          {
            winner = "computer";

          }
          else{winner="You";
          }
  return winner;
  }
public static String update(String winner,int computerWins,int playerWins,int tie){
    if (winner.equals("computer")) {
      computerWins++;
    }
    else if (winner.equals("you")) {
      playerWins++;
    }
    else{tie++;}
     return "draw";

    }
  }
