Answer
nextInt() leaves a newline in the buffer. Frame the concept in practical terms so you can explain it during interview discussion.
After using 'nextInt()', a newline character remains in the input buffer. If you follow it with 'nextLine()', it will read this newline instead of waiting for user input. To avoid this, call an extra 'nextLine()' to clear the buffer.
