Semester.About C-language is that i have good concepts(THANKS GOD).

Now i am found of JAVA to crazy extent.

Sir since i have read the book "THINKING IN JAVA" after reading preface of book at Bruceeckel.com, i felt that if i could't purchase your book then i may left with great deficiency as Electronic Book is not easy to read.
So i purchased the book and i have read eight chapters.

All concepts are clear But:

Only one concept of "UP CASTING" is teasing me too much and now i am fed up with that as all other concepts for example inheritance,interface is relating to "UP CASTING".
