string - Comparing dates in Java -


i read date functions cant think best way solve problem.

i have couple of dates database string , want compare may current date. using compareto, there problem using function guess because of comparing strings.

this function:

public int datecompare(string today, string date2){     return today.compareto(date2); }

and when use in sample dates:

datecompare("04/19/2013","04/18/2013");

it returns 1, , when change value of first parameter "04/20/2013" still returns 1.

please help...

java has date object. should using instead.

import java.util.calendar; import java.util.date;  public class comparedates {      public static void main(string[] args) {         // create calendar, default today         calendar cal = calendar.getinstance();         // subtract 1 day         cal.add(calendar.date, -1);         // compare result (1)         system.out.println(datecompare(new date(), cal.gettime()));         // add 2 days         cal.add(calendar.date, 2);         // compare result (-1)         system.out.println(datecompare(new date(), cal.gettime()));                 }      public static int datecompare(date today, date date2) {         system.out.println("compare " + today + " " + date2);         return today.compareto(date2);     } }

you make use of date api , use before , after...

date = new date();  calendar cal = calendar.getinstance(); cal.add(calendar.date, -1); system.out.println(now + " isbefore " + cal.gettime() + " = " + now.before(cal.gettime())); system.out.println(now + " isafter " + cal.gettime() + " = " + now.after(cal.gettime())); cal.add(calendar.date, 2); system.out.println(now + " isbefore " + cal.gettime() + " = " + now.before(cal.gettime())); system.out.println(now + " isafter " + cal.gettime() + " = " + now.after(cal.gettime()));

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers ...
