Compare Two String Date and Time in android?

Question

try{

     SimpleDateFormat formatter = new SimpleDateFormat("dd/MM/yyyy");


     String str1 = "12/10/2013";
     Date date1 = formatter.parse(str1);

     String str2 = "13/10/2013";
     Date date2 = formatter.parse(str2);

     if (date1.compareTo(date2)<0)
      {
         System.out.println("date2 is Greater than my date1");                         
      }

    }catch (ParseException e1){
        e1.printStackTrace();
    }

You can use following:

    public static boolean CheckDates(String startDate, String endDate) {

    SimpleDateFormat dfDate = new SimpleDateFormat("dd-MMM-yyyy");

    boolean b = false;

    try {
        if (dfDate.parse(startDate).before(dfDate.parse(endDate))) {
            b = true;  // If start date is before end date.
        } else if (dfDate.parse(startDate).equals(dfDate.parse(endDate))) {
            b = true;  // If two dates are equal.
        } else {
            b = false; // If start date is after the end date.
        }
    } catch (ParseException e) {
        e.printStackTrace();
    }

    return b;
}

String pattern = "dd-MM-yyyy HH:mm:ss";
SimpleDateFormat dateFormat = new SimpleDateFormat(pattern);
Date one = dateFormat.parse(Date1String);
Date two = dateFormat.parse(Date2String);

Now you have two Date objects, you can compare them.

You can convert String to Date like this:

    String str = "12/12/1912";
   SimpleDateFormat formatter = new SimpleDateFormat("dd/MM/yyyy");
   Date date = formatter.parse(str);

And back to String

    SimpleDateFormat formatter = new SimpleDateFormat("dd/MM/yyyy");
   System.out.println("Date is : " + formatter.format(date));

And Date has before and after methods and can be compared to each other.

By the way there is also a library called Joda, you can also check it out.
