hello everyone,


i have a string of the form "03July2010 13:50:50 "
i want to convert this string to number(integer) so that i am able to
apply relational operators like(>,<,>=,=) to get the result.

could anyone help me out with this.

thanks.

You need to look at the SimpleDateFormat class, where you can parse the Date/Time string into a java.util.Date - which you then can get as a long.

You create a SimpleDateFormat object on which you set a Date/Time pattern matching your string input (see the SimpleDateFormat API for a list of available pattern elements, and how they are used), then you parse your string date/time, and finally you get the date/time as a long from the Date object.

Like this sample:

DateFormat df = new SimpleDateFormat("yyyy-MM-dd");
Date d = df.parse("2010-07-03");
long dateTime = d.getTime();
