Thanks a lot for clarifications

Thanks,
Can you please give any one error which we cannot handle

Hi,

Can we catch error in java code like, can we catch OutOfMemoryError, ThreadDeath etc.

Thanks,

Like in spite of getters/setters can we directly deal with instance variables?

Thanks for the reply.

I totally agree with you that java does not support multiple inheritance but got confused when read everywhere that in java multiple inheritance can be archived by interface.

Can you please put some light on that?

Thanks,
Ram

Hi,

I have one class B and i want to use some artifacts which are available in class A like methods and instance variables.
I just want to discuss that in this situation which is better is-a or has-a

Thanks,
Ram

Thanks everybody..... That clarify my doubt.

Hi,

I was just come across one confusion. Below please see the code:
import java.sql.SQLException; public class InternTest { public static void main(String h[]){ A a = new B(); System.out.println(a.test()); System.out.println(a.i); } } class A{ private int i = 0; public String test(){ return "--- Class A ---"; } } class B extends A{ int i = 1; public String test(){ return "--- Class B ---"; } }


In above code i am getting compile time because in main() method on line System.out.println(a.i); it is not able to get the value of i.

Thanks,
Ram

Thanks for your answer. After putting where clause also i am having 1 million of records. Then how to restrict.

Hi,

I need to check that does something exist in some specified table or not. For that i can run query like select * from mytable ... but my problem is that mytable consist 10 Lakhs of records.

I only need to check that is any single record exist or not.... Can i use setFetchSize() or something else... can you please suggest what policy should i opt to improve performance

Thanks
