title: Incompatible types - found java.lang.String but expected int, in java
body: <p>Displays the date 100 days from today, the day you were born, and the date 10,000 days after your birth date. I've done all that, but i want to take it a step further, i want the user to be able to input the number of days from today that he/she wishes to know the date of (if that makes any sense at all...). Here's what the part of the code i'm working on looks like:</p>
  
  <pre><code> public class calendarProjectTest
      {
      public static void main(String[] args)
      { GregorianCalendar cal = new GregorianCalendar(); //declare today's date
      GregorianCalendar myBirthday = new
      GregorianCalendar(1990, GregorianCalendar.JUNE, 9); //declare my birthday
      System.out.println("Please enter a number greater than 0:");
      Scanner keyboard = new Scanner(System.in);
      String number = keyboard.next();
      int value = number;
      cal.add(GregorianCalendar.DAY_OF_MONTH, number);
  </code></pre>
  
  <p>I'm using Bluej and it says, "incompatible types - found java.lang.String but expected int"
  I'm at a loss. i don't have any idea what to do. any advise would be great. and yes, i know there are no end brackets.</p>
