Hi Deepa ,Pankaj ,Rakesh
read the following post about it in JLS
posting the relevent portion
Refer JLS- 3.9
"While true and false might appear to be keywords, they are technically Boolean literals (�3.10.3). Similarly, while null might appear to be a keyword, it is technically the null literal (�3.10.7). "
thus true false and null are not Keywords.they are literals...
Some one had a talk with Michael Ernest- (of RHE) earlier.
Michael then had said that such confusing questions will not be coming in real Exams...I am sorry I dont have a link to that post...( HOpe someone can provide that )
Perhaps, I saw that in Javacertstudy group.
HTH
