even i want to know about the 3 rd and the 4th questions....i.e. the freuency of the word....i got it in the exam in the prep, but not getting now!! arggg!!!

yeah pattern questions will come...
1)no...not heard of them at all.
2) pass the string into a charArray.....str.toCharArray();
then find the length of the array, either using length funct, or by using count variable.

5) i also dont know how to print the patterns...well, i am going to learn whatever is there in my text...but, one such question is sure i think...
