Hi,

If we are giving--
List<Smtable> svalues = new List<Smtable>();
it will show some Error.
But...
if we are creating an object in ArrayList like this--
ArrayList<Smtable> svalues = new ArrayList<Smtable>();
no Error is shown.

Why is it so? can't we create an object in type List?

And when it is given like this---
List<Smtable> smlabels = jobmgr.getSmvalues();
it wont show any Error and works fine.

Could anyone help me?


Thanks

Hi,

Suppose I've 2 interfaces having same method, say A();.
If one class implements both the interfaces, then what will happen when its object calls the method A()?

could anyone clear my doubt?

Hi,

As I'm working in a Real Time Project, the database now contains 22digit indexes. We're using Oracle10g.
I want to know, whether we can set the Index to reset(to start from 0th Index) when it reaches the limit.

Please help me...

ThankYou Ritchie

But I've one doubt; the Class variable/Instance variable is also having their scope throughout the class/object. Right?


Thanks

Hi,

I read in a book that, Instance variables are Non-static fields.
And Class variables are Static fields.
Also Parameters are classified as variables and not fields.

Could any one tell me what's the difference between a Variable and a Field?

I studied in Java, that each Java file should have a Main method. And the name of that class in which the main is written should be the file name.
But in the development of a web application, it is not followed. Here everything is a file named web.xml
Why is it so? Then how the files are executing?

Could anyone help me?
