[3/3/2006] 8th week's material is posted. We will review the 2nd-midterm questions in the beginning and then practice a program to check if a number is prime.

[2/24/2006] OK, I figure out how to check if the input is an integer. My approach is to use hasNextInt() to see if the input is an int, if yes then I read (use nextInt()); otherwise, I skip that input and continueously ask the user to input again. Please check updated code again. Btw, there's one minor error we did in discussion, go to Line 37, we need to update 'guess' value when we're done checkRange() otherwise the 'guess' is always an old one.
