help to show integer value in a time format - newbie

[mumbaimacro]

dear all

i am n a situation to display from a int value into Time format,
is there any possiblity of using existing java util classes? or i need to rite my own class?
kindly help me to get a sloution ,

Can you describe your problem more clearly.
What should the output be if the program was given the following

• 2
• -1
• 0
• 1945
• 1999876
• Integer.MAX_VALUE

which are all valid integers?

Ans:

the valid input in the above list is --> 1945 & the o/p will be like this 7.45 pm


hi ,

the integer value size is 4, ( which i stored in table as Time)
for example

if time is 1500 in table >>
then i have to show , something like this format 3.00 pm in screen

Well now don't you think that is a better description of the problem now?
You can write your own method or use the GregorianCalendar class.
Better do this in steps.
First determine whether the input is valid or not (must be positive and must contain 4 digits).
Then split the digits by half into hours and minutes. You can then either set those into a gc to get the am or pm or use a if else to do it yourself manually.

But then the value '2' should be valid as well: two minutes past midnight.
For an int value x, x/100 represents the hours and x%100 represents the
minutes.

thanks for the suggestion sir, i will write a method to do this.

Have a look at Jos' post above and think about it as well.
It's you who comes up with the rules but make sure your rules are workable. If you restrict the numbers to 4 digits will your program be easy to work with?

u r correct, if dere s a requirement to include seconds then the size will be 6

in that case for eg : 194512 and i need to format 19:45:12 (hh:mm:ss)

then i have to frame the method....

I'd say four digits or less, more exact the number must be < 2400 for starters.

I'd say forget about the thing entirely; store date/time values as date/time types
and use a SimpleDateFormatter for the display of it all. That way you don't have
to write your own classes and you can handle everything you ever have to handle.

I hope no new information about the problem emerges again ...

I suspect the OP to be a customer; they always do that and they're driving me crazy ;-)

me: So you're absolutely sure that what I wrote down are all your requirements?
customer: Yes.
me: Really absolutely positively sure? We can go through it one more time again.
customer: not needed, this is it; I'm sure.
me: Really, really, really sure?
customer: yes.
me: Ok fine, I'm glad we settled the entire issue.
customer: me too, I'm glad we can take the next step.
me: yup, see you next week then.
customer: yes, fine; oh, btw we decided that we want all the menus coloured green
and while I'm at it the application should automagically smell that we want the reports
to be produced even if we haven't supplied all data yet and we want the application
to be able to start Solitaire as well, but only for my account. And my nephew told
me that Java sucks so we don't want that; we do want J2EE technology instead
because we're a modern company. And we want Oracle as well instead of DB2.
On a floppy disk please so I can take it home with me for security reasons.

dear all

sorry for the late reply....as i cant change ma existing data type since its an production data...only thing writing own class..
Moreover i m a new bie , so slow to get the things...

thanks for replies

Ok, so a date/time value is stored as an int. So far so good; What exactly is
stored in that int? The time of the day? Are seconds, milliseconds included?
We need to specify exactly what is in that int and how time is encoded as an
int value before we can start designing or even implementing fancy classes.

Right now we haven't even touched the specification/requirement stage which
has to be completed before we can even design something.

Field Size
Time 6


In that case for eg : This value s stored from other program based on some conditions

Value for this field is 194512 in table and display will be either of the one below , i am not sure which one s appropriate or easy to show from the below formats

19:45:12 (hh:mm:ss)
or
07:45 pm

kindly suggest me

thnks

You mean the field size is 6 or less?
I suggest you work on the allowable input first and how it maps to time. Displaying in 12 hour or 24 hour is easily done as the the last exercise.

actually that time s stored by a cobol prgm , where its updating table with 6 digits

TIME 9(006)

but when i look in sybase table desciption its showing the following

TIME int 4

also all d data i am having for this field n sybase shows

TIME 194512

so confused to tell u the correct size sir!!!!!!!!!

But if the decimal representation of the number is equal to, say, the display of
a digital clock, all you have to do is something like this:

DecimalFormat df= new DecimalFormat("00,00,00");
DecimalFormatSymbols dfs= new DecimalFormatSymbols();
dfs.setGroupingCharacter(':');
df.setDecimalFomatSymbols(dfs);
...
// and format away using df and your int values

Jos

ps. read the API documentation for those classes; most likely I made a few
typos above; it was from the top of my head.
