Hi,
Is there any API existing which can trap the standard errors and can
display on demand. I am using an IBM API which sends the errors to
stderr which I want to trap and show to the client on demand.
Many Thanks,

Say what?!? I've written tons of Java applications that have more than
one public class.
I think he meant if you have more than one class in your FILE then only
one of them can be public.

why it come out 0? I guess variable i has not have been initialized, so i--

you guys mean i=0 is system default?
Apparently so. I wouldn't have believed it but it just worked, under JDK

You can use "{" and "}" to create blocks.
Really some of these java questions can be answered quicker if you get a reference manual (like the Java in a Nutshell book)

That would be because Getters and Setters are public methods
rather than
classes.. no? It seems the original post was pointing out
that there can be
only one public class which calls the main method.

If you ever want to know how your algorithm became to be, try inserting some
System.out.println(algorithmcalculations);
or
out.println(algorithmcalculations);
Then you will see how the values added etc

No, when you do a system.out.println();
In your ide, your suppose to see the print statements, thus leading you how

So for example

Yep. The shift is bits, so the 0x0010 must be interpreted as

Thus the result of the right shift operation is
