but why it is giving error at JTable constructor???

thanks for your reply
i got
"java.lang.ClassCastException: java.util.Collections$SynchronizedRandomAccessList"
exception
don't know where exactly it's wrong.

pre=post;
i++;
}
}




//System.out.println(rowdata.toString());

jf.add(jtb);

hi frnds,
today i cleared scjp1.5 with 95%.

I got it..
Thanks for the explanation.

Collection<?> c=new ArrayList<String>();

we cannot add anything to c.Then what is the use of referring object to c??

why is it ambiguous if we pass null to append method??
