Question

1. the person will think a number between 1-100. The Questionnaire can ask n number of condition, i.e the number is even or odd, the number is perfect square or prime number, sum of squares etc.

Answer 1

It is certainly possible to find a number between 1 and 100 by asking 100 questions, namely:

1. Is the number one?

2. Is the number two?

   etc., etc., etc.

It is possible to do it with 7 questions by binary search. Writing the number in base 2, ask:

1. Is the units bit one?

2. Is the twos bit one?

3. Is the fours bit one?

   etc., etc., etc.

I don't know anything about Java code, but that's for a different website, anyway.
