I have been working on this program for about a week now and I think I have it down pack. The issue I am having when I ask the user at the beginning of the game (human vs computer) everytime I run the program it asks me what my name is again. Here is what I have thus far:

 import java.util.Scanner;  

 public class Assignment  
 {  
     Scanner usersName;  
     Boolean humanTurn = true;  
     Boolean computerTurn = true;  
     int dice;  
     int humanTurnPoints, computerTurnPoints;  
     int humanTotalPoints = 0;
     int computerTotalPoints = 0;
     private Scanner keyboard;
     private Scanner key;   

     //System.out.print("Please enter your name: ");
     //usersName = new Scanner(System.in);  
     //setStart(usersName.nextLine());

     public void roll()  
         {  
         dice = (int)(Math.random()*6) + 1;                   
         }      

     public int humanTurnScore()  
         {  
             {  
                 humanTurnPoints = dice + humanTurnPoints;  
                 System.out.println("You threw: " + dice);
                 System.out.println("You have scored: " + humanTurnPoints + " in your turn.");  
             } return humanTurnPoints;  
         } 
     public void humanTurnZero()
     {
        humanTurnPoints = 0;
     } 

     public int computerTurnScore()  
         {  
             {  
                 computerTurnPoints = dice + computerTurnPoints;  
                 System.out.println("Computer has scored: " + computerTurnPoints + " in its turn.");  
             } return computerTurnPoints;  
         }     
      public void computerTurnZero()
         {
            computerTurnPoints = 0;
         } 

     public Assignment()  
     {  
         humanGame();  
         if(!humanTurn)  
         {  
             computerTurn();  
         }  
     }  
     public int humanGame()
        { 

         System.out.println("To start the game please press 'r'.");  
         key = new Scanner(System.in);  
         String start = key.nextLine();  
         if(!start.equalsIgnoreCase("R")) 
         {
                System.out.println("Make sure you are pressing 'r'.");
                humanGame();
         }

         if(start.equalsIgnoreCase("R"))
            {                          
                         System.out.println("You pressed 'r'.");  
                         System.out.println("Lets start.");           


             do{  
                 roll();    


                 if(dice == 1)  
                 {  
                     System.out.println("You got 1 and you lost your turn.");
                     System.out.println("Computer's GRAND TOTAL score is: " + computerTotalPoints);
                     humanTurnZero();            
                     computerTurn();  

                 }  
                 else if(dice != 1) 
                 {

                     System.out.println("You can hold or roll again.");  
                     System.out.println("To roll again press 'r' or 'h' to hold.");  
                     keyboard = new Scanner(System.in);  
                     String choice = keyboard.nextLine();

     return dice;  

 }     


 public static void main(String[] args)  
 {  
     new Assignment();  
 }  
 }  

I commented out (up close to the top of the program) where I am asking the user at the beginning of the program what their name is. I actually need in all the System.out.println where it says 'You' I need it to say the usersName.

Would someone please help me with this program. I know someone is kind enough to help me out here.

Thank you in advance.

You need that the program ask the name and latter replace 'You' for this name? (Sorry for my english)

Somethin like that?:

import java.util.Scanner;

public class Assignment
{
    //Scanner usersName;
    String usersName="";
    Boolean humanTurn = true;
    Boolean computerTurn = true;
    int dice;
    int humanTurnPoints, computerTurnPoints;
    int humanTotalPoints = 0;
    int computerTotalPoints = 0;
    private Scanner keyboard;
    private Scanner key;

    // System.out.print("Please enter your name: ");
    // usersName = new Scanner(System.in);
    // setStart(usersName.nextLine());
    public void roll()
    {
        dice = (int) (Math.random() * 6) + 1;
    }

    {

            System.out.println(usersName + "threw: " + dice);
            System.out.println(usersName + "have scored: " + humanTurnPoints + " in your turn.");
        }

    }

Actually, I think I just saw my solution (or the error any way).

I need to put this in

public Assignment(String xUsersName)
      {
      usersName=xUsersName;
      humanGame(); 

And fix some spacing errors. Thank you for everyone's help. It is nice to be able to have a third eye in programming. I am still a beginner but I am determined to work this out. I am sure I will be back. Thanks again.
