Hi
I have also joined the community of SCJPs on Nov 18,2000.
I am satisfied and happy with the score of 76%.
With the help of my one year old daughter who used to constantly turn my pages, I enjoyed studying RHE( the only book i studied apart from the material on the web)
I concentrated on IO the last 2days as I was poor in it and scored 100%. So if u feel a topic is difficult, dont let it master over you instead master it and u will crack the exam.
On the night before the exam , I went thru marcus green's tutorial and the topic wise questions, which I feel helped me buid confidence.
I did rather very badly in awt section.the questions on layout.
threads was OK. I got theory many theory questions about wait() sleep() yield() etc.
Time was enough, i had 20 mts to review.All the SCJPs earlier have given almost the exact picture of the exam.
I am very grateful to JavaRanch and its members. I was very much motivated to write this exam after visiting this site.
All the best to the SCJP aspirants in their exam and SCJPs in their career.
Regards

We cannot declare static variables inside a method
coz the scope will be limited to that method

Aparna
If so, will it call any static method called or only main method?

I tried running just the innerclass but it always gives the exception in thread main Nosuchmethod error
I tried something like
public class Test {
public class Inner1{};
public static class Inner2{}
}
java test$Inner1
java Test$Inner2
<Quote>
if you run obj1$obj2 you get
</quote>
can you or somebody tell me why I am getting an exception
Thanks
Anitha

I agree with everything except that the object which can be GCed is Nick and not Jason
But the answer is 1
Congratulations kourosh
Good luck in your career

1)The order of the modifiers does not matter.
final public static void main (String args[]) or
static final public void main (String args[])
is fine

2)void main() , int main(int i) etc. work fine but they do not act like the main that we want.
You would easily know the answer by compiling and running the code. As for the explanation, it goes like this...

Strings are immutable i.e., they cannot be changed.
composite.concat("world") does not change composite
if it was composite=composite.concat("world") then it would have changed to "hello world"

String space = " ";
String composite = space + "hello" + space + space;
// " hello "
composite.concat("world");
//doesnot concat since strings are immutable
String trimmed = composite.trim();
// removes spaces "hello"
System.out.println(trimmed.length()); 5
I agree with Kourosh regd answer to Ques1 . The string "bye" is
referenced by d before b points elsewhere.
so I think it is eligible for GC only after line (3) when d no longer points to it.
public class test {
public static void main(String args[]) {
Integer intObj=Integer.valueOf(args[args.length-1]); //args[1-1] will have 2 intobj's value will be 2
int i = intObj.intValue();//i=2
if(args.length > 1) //False
System.out.println(i);
if(args.length > 0) //True
System.out.println(i - 1); //2-1 ie 1 will be printed
else
System.out.println(i - 2);
}
}
I would like to add that
methods in an interface are implicitly public and abstract

Originally posted by Bin Zhao:
Yes,variables in interface implicitly are public,static final.

In general what modifiers are allowed to be used if you want to overide the default modifiers.
thanks


In general default,protected or public are allowed to override a method with a default modifier

Aruna,
In your code the error I think is only because you are making it more restrictive(ie private) but not because you are overriding a static method.
The rules that I learnt are that
A static method cannot be overridden as non-static.
A non static method cannot be overridden as static.

The error must be because the System.out.println(m2 );
was directly under the class instead of being in a method.

The RHE book says
there is no guarantee that the listeners will be notified in the order in which they were added.
So I think that the answer should be false
