Re: converting to Julian Dates

[Andras Balogh]

Hi Jeetandra!

 

I think U should use GregorianCalendar instead of Date.

 

Here is a source code:

 

 

GregorianCalendar g=new GregorianCalendar();
g.setLenient(false);
g.set(1999,01,29); 
System.out.println(g.get(GregorianCalendar.DATE)); 

 

As U see  the date is set to 1999 february 29 (wrong date).

 

This code throws IllegalArgumentException at runtime.

 

So u should check the date is if corect like this and if not send an error page

else U can format this date.  You can get a Date object calling g.getTime();

See the docs for GregorianCalendar for more info.

 

Don't forget g.setLenient(false).

 

p.s. If something is not right please fill free to contact me.

 

What about the Please wait window that U have asked last time ? Did U use my version ?

 

Best wishes,

                    Andras
