Issue with Date objects

[liliya woland]

Hi all, I have this simple method converting String dates to Dates to Strings of another format. For some reason the final result is one date for both Strings. I want to understand what's happening in the method that causes such behavior. Much appreciated.
Output:
start: 01/30/2012 -->January 30, 2012
end: 09/30/2012 -->January 30, 2012

Method:

    private static void buildMethodologyPage(String startDate, String endDate)
    {
		try
		{
			
String test0 = new SimpleDateFormat("MMMM dd, yyyy").format(
    new SimpleDateFormat("mm/dd/yyyy").parse(startDate));

String test1 = new SimpleDateFormat("MMMM dd, yyyy").format(
    new SimpleDateFormat("mm/dd/yyyy").parse(endDate));	    

System.out.println("start: "+startDate+" -->"+ test0);	
System.out.println("end: "+endDate+" -->"+ test1);	
	
		}catch(Exception e){e.printStackTrace();}	
    }

Note: m = minutes

Ok, now I'm seeing more of the issue. This convertion of 09/30/2012 -->January 30, 2012 is happening regardless of having or not having another date. Hm...

to further emphasize Henry's point...

m is not the same thing as M.

Therefore, mm is not the same thing as MM.

Got it, thanks a lot!
