Core Java Tutorial

Hi to all...........!

i m just gonna write the tutorial on Core Java which i learned 4 months ago, you may think why i m writing this ,since  any one can get many tutorial on java from Google engine, u r right becoz i was same like you,bt during  learning i realize some think is there which we can't learn from text book or tutorial, so whatever problem i faced that i will include here,and another reason is that i want to revise all those thing,actually i m guy who plans a lot but not doing thing  that much,i started learning java and planed to write the SCJP exam bt i didnt get time bucoz  u know we have a lot of stuff other than study,

                                                                   Any way i will start from basic so that it will be benefitial for beginner too,one more thing i need help of u ppl also n if any error , mistake or confusion then we can discuss it

also if it is benefitial  then plz reply

thanks
