Thread: Completely lost, creating a bar graph

i wrote this code:

   import java.text.DecimalFormat;
   import java.util.Scanner;
 
   public class salary
   {
      public static void main(String[] args)
      {
      //declare variables
         int years = 1,
            maxValue;
         double salary = 500;
         double averageSalary = 0;
         double totalPay = 0;
 
      //Create decimal formatter
         DecimalFormat formatter = new DecimalFormat("$0,000.00");
 
      //create a scanner
         Scanner keyboard = new Scanner(System.in);
 
      //Receive the number of years to work
         System.out.print("How many years will you work? ");
         maxValue = keyboard.nextInt();
 
      //Determine is years are correct
         if (years < 1 || years > 60)
         {
            System.out.println("Years must be between 1 and 60");
         }
         else
         {
         //Return Salary table
            System.out.println("Year \t\tSalary Earned");
            System.out.println("--------------------------");
 
            for (years = 1; years <= maxValue; years++)
            {
               System.out.println(years + "\t\t" + (formatter.format(salary *= 2)));
               totalPay += salary;
               averageSalary = totalPay / years;
            }
 
         //display totals
            System.out.println("\nTotal pay: " + (formatter.format(totalPay)));
            System.out.println("Average salary: " + (formatter.format(averageSalary))); 
         }  
      }
   }

this code runs correcty as is, but how do i change it to create instead of a table with a salary a table with ***
for example
current out put would be :

----jGRASP exec: java salary
How many years will you work? 4
Year Salary Earned
--------------------------
1 $1,000.00
2 $2,000.00
3 $4,000.00
4 $8,000.00

Total pay: $15,000.00
Average salary: $3,750.00

----jGRASP: operation complete.

desired output would be

----jGRASP exec: java salary
How many years will you work? 4
Year Salary Earned
--------------------------
1 *
2 **
3 ****
4 ********

Total pay: $15,000.00
Average salary: $3,750.00

----jGRASP: operation complete.
