Thread: its crazy

how do i get "its crazy" if gas goes past 4 in the avg?

import java.util.Scanner;
 
public class mk2
{
public static void main(String[] args)
{
new mk2 ();
Scanner input = new Scanner( System.in );
 
      double total;
      double gasCounter;
      double gas = 0;
      double average;
 
      total = 0; 
      int valueCounter = 0;
 
      System.out.print( "  Enter gas price for octane 87, or -1 to quit: " );
      double value = input.nextDouble();
 
      while ( value != -1 )
      {
      total = total + value; 
      valueCounter = valueCounter + 1; 
 
 
      System.out.print( "Enter gas price for octane 89, or -1 to quit: " );
      value = input.nextDouble();
 
      while ( value != -1 )
      {
      total = total + value; 
      valueCounter = valueCounter + 1;
 
      System.out.print( "Enter gas price for octane 91, or -1 to quit: " );
      value = input.nextDouble();
      } 
 
 
      if ( valueCounter != 0 )
      {
      if ( gas>=4.00)
      {
    	 total = (double) total;
      }
      else if(value<4.00)
      {
    	  total = (double) total;
    	  }
    	  else
    	  {
    	  System.out.println("enter the valid ones");
    	  }
    	  }
 
    	  System.out.printf(" The average gas price is $%.3f\n", total/3);
 
      }
      }
