one of my frends told me that taking SCWCD certification first is more appropriate than SCBCD ..

Kindly help to spot the distinction as i am in my first stage of learning J2EE !

i think the compiler doesnt object for

Throwable , Exception,( Error & RuntimeException and its subclasses )
( to be given in the catch clause ) when try is given as :

try {
}
catch( ) { }

however it objects for All CHECKED Exceptions ...

(Correct me if am wrong)

Hema
A progmmer has written the following class to prevent garbage collection of the objects of this class. Is he mistaken?

class SelfReferencingClassToPreventGC
{
private SelfReferencingClassToPreventGC a;
Object obj = new Vector();
public SelfReferencingClassToPreventGC()
{
a = this; //reference itself to make sure that this is not garbage collected.
}

public void finalize()
{
System.out.println("Object GCed");
}
}


Answer provided :

Explanation:
Yes, he is definitely mistake. Because, all he is creating is a circular reference, but such references do not prevent an object from garbage collection. Basically, if B is only refereded to by A and A is eligible for GC, then B iseligible for GC to. So, if A refers to B and B refers back to A, this arrangement does not prevent them from being garbage collected

Could anyone explain the actual concept ..
Thanks for the info.. regarding the book..
and i am practising to work with Collections ... but due to the assorted methods in the class , i found it quite difficult to remember all of them.. anyway my practise only will make it perfect .. Thank you
