Hello All,
Can somebody please guide me on my below queries?

1. As I understood, in Part 2, different UML diagrams need to be provided for the downloaded case study. My question here is, which IDE to be used to develop these UML diagrams?

2. After getting the voucher, can I download the assignment from internet or I need to go to prometric center for download?

3. After finishing the assignment, how and wht to bundle in case we are using tool to develop the UML diagrams?

4. Can we also upload word document along with UML diagrams in case we need to attach additional data?

Thanks in advance.

Thanks.

Solution:

BigInteger bigInt = new BigInteger("100010001000100010001000100010011000011100010001000100010001000100010011000011111111111111111111111111111111111111111111111100",2);

BigDecimal bigDec = new BigDecimal(bigInt);

Then use this BigDecimal object to persist the data in Number type in oracle database table.

Hi All,

I have a Date stored in GMT format in database. Now I need to display this date to user depending on his/her LOCALE. I found SimpleDateFormat and few other classes to convert the Date Format, but I am not able to find how to change the Date value as per user locale.

Example:
Date in database : 19 August 2004 6:30 PM

Date for User from India should be : 19 August 2004 1:00 PM

How to achieve this .???

TIA,

I have a stateful session ejb which is calling stateless session beans for some business processing.

Should I use helper classes instead of stateless session beans ..???

Hi All,

I was wondering if all the getXXX methods in the Value Objects should be declared as final.

I mean, is there any performance gain by making the get/set methods as final. These value object classes are used inside my ejb beans.

I have a collection. Should I use Iterator or Enumeration or for loop to iterate through all objects of this collection ?
