Hi All,
I am facing one problem in my application only some times.
The problem description shows it is regarding cursors opened (ORA-01000).
Please see the code below...
closeDBStuff(Connection con, Statement pStmt, ResultSet rs){

if (rs != null)
rs.close();
if (pStmt != null)
pStmt.close();
if (con != null)
con.close();
con=null;
rs=null;
pStmt=null;
}
I am calling this method from all my methods from a finally{} only.
My doubt is: Suppose if i created an object/ref to PreparedStatement in one method and in that finally i am calling closeDBStuff() method by passing this PS ,it is not giving any error even this closeDBStuff() is expecting Statement obj.but my doubt is whether it is really closing that obj.
Please help me in this regard...

Hi,
I have a doubt in the answer for the below.I read this question from one mock exam.
Which of the following statements about interfaces is correct?


A Due to Java's principle of single inheritance, a class declaration can only name one interface.

B All methods in an interface have default accessibility unless declared otherwise.

C All methods in an interface have public accessibility.

D An interface may not contain any variables.



Correct option "C"
A - No, a class declaration may include multiple interfaces.

B - No, all methods in an interface are implicitly public.

C * Yes, all methods in an interface are implicitly public, no matter how the interface itself is declared.

D - No, interfaces may define static final variables

They provided check box ,to select multiple.
My options are C,D
Please tell me Wht is my mistake

Hi Swarupa,
Are U sure ?I think it will creates only one class i.e Test.class.
Thanks a lot
Hi Swarupa,

"You are compiling file Name.java and java compiler gerates the Test.class and Name.class files so when u run the java program using Name class it shows NosuchMethodError because it doesnot have main method and u r trying on Name class ,Try to run program using java Test"

Are you sure? If we compile file Name.java and java compiler generates the
"Test.class and Name.class" for the above code.
According to me it generates only one class file with name Test.class.

Correct me if i am wrong

Thanks a lot

But you explained only what i know.
How to call the constructors explicitly,here we will use this...am i correct,but how.
wht is current object...

Thanks a lot

Hi All,
Actually what are the main advantages and disadvantages of "this"?
I know few,
to remove name abiguity for compiler,means this.name=name situation,and calling a constructor but dont know how.
Please tell me,actually what will happen internally when we use "this".
And correct me if i am wrong,"this" means currently invoking object.
what does it means?

thanks a lot
