Difference in days between two dates in Java?

Question

I need to find the number of days between two dates: one is from a report and one is the current date. My snippet:

  int age=calculateDiffer

Do you think this is a threading issue? How are you using the output of this method for example? OR

Can we change your code to do something as simple as:

Calendar calendar1 = Calendar.getInstance();
    Calendar calendar2 = Calendar.getInstance();
    calendar1.set();
    calendar2.set();
    long milliseconds1 = calendar1.getTimeInMillis();
    long milliseconds2 = calendar2.getTimeInMillis();
    long diff = milliseconds2 - milliseconds1;
    long diffSeconds = diff / 1000;
    long diffMinutes = diff / (60 * 1000);
    long diffHours = diff / (60 * 60 * 1000);
    long diffDays = diff / (24 * 60 * 60 * 1000);
    System.out.println("\nThe Date Different Example");
    System.out.println("Time in milliseconds: " + diff
 + " milliseconds.");
    System.out.println("Time in seconds: " + diffSeconds
 + " seconds.");
    System.out.println("Time in minutes: " + diffMinutes 
+ " minutes.");
    System.out.println("Time in hours: " + diffHours 
+ " hours.");
    System.out.println("Time in days: " + diffDays 
+ " days.");
  }
