    Default Generate a random number

    I am doing a program and i ahve some problems here.
    this is what i have so far.
    Java Code:
    import java.util.Scanner;
    import java.util.*;
    import java.io.IOException;
    import java.io.InputStreamReader;
    import java.io.Reader;
    
    
    public class Test
    {
    public static void main(String[] args) throws IOException
    {
    int total = 0;
    
    int number = 0;
    int numbera = 0;
    
    while (total < 12)
    {
    for (int i = 1; i < 2; i++)
    {
    number = 1 + (int) (Math.random() * 6);
    
    
    }
    System.out.println("You want to roll again, y or n");
    Reader r = new InputStreamReader(System.in);
    char c = (char) r.read();
    String s = new Character(c).toString();
    if (s.equalsIgnoreCase("y"))
    {
    total += number;
    
    }
    else if (s.equalsIgnoreCase("n"))
    
    {
    total = number;
    }
    
    System.out.println("The total number of spots are " + total);
    }
    
    
    System.out.println("YOU LOSE!!!");
    
    
    {
    
    
    }
    
    }
    
    
    }
    after i press "n" it should automatically be the computers turn.
    this is are rules of the computer.
    1. Should generate a random number between 1 and 6 if it generates anything that =>8 it should stop and compare with my score.
    2. If it generates anything > 11 it losses (if i dont generate anything >11)
    3. Compares who wins at the end (player or computer).

    Thanks

    It seems like your program is running, what's wrong with it?

    Java Code:
    import java.util.Scanner;
    import java.util.*;
    import java.io.IOException;
    import java.io.InputStreamReader;
    import java.io.Reader;
    
    
    public class Test
    {
      public static void main(String[] args) throws IOException
      {
        int total = 0;
        int totala = 0;
        int number = 0;
        int numbera = 0;
    
        while (total < 12)
        {
          for (int i = 1; i < 2; i++)
          {
            number = 1 + (int) (Math.random() * 6);
            numbera = 1 + (int) (Math.random() * 6);
          }
    
          System.out.println("You want to roll again, y or n");
          Reader r = new InputStreamReader(System.in);
          char c = (char) r.read();
          String s = new Character(c).toString();
    
          total += number;
          totala += numbera;
    
          if (s.equalsIgnoreCase("y"))
          {
            System.out.println ("The total number of spots are " + total);
          }
          else if(total > 10)
          {
            System.out.println("YOU LOSE!!!");
          }
    
          if (s.equalsIgnoreCase("n"))
          {
            System.out.println("The total the computer has generated are " + totala);
          }
          else if (total > totala)
          {
            System.out.println("Well done you Win ");
          }
          else if (totala > total)
          {
            System.out.println("You have lost Better luck next time");
          }
          else if (total==totala)
          {
            System.out.println("Game Is Drawn");
          }
        }
      }
    }

    If you're unsure if it's working or not, put in some System.out.println(); printing out variable names as they come up to make sure it works.

    Basic Debugging. I know in some IDE's you can even step through a program and it will show you what variables are currently in use or have been assigned.
    Greetings.
