    Answer: A. True

    Explanation:The Scanner class methods are methods in java. util, which allows the user to read values of various types. This problem occurs as you hit the enter key, which is a newline / n character. nextInt () consumes only the integer, but it skips the newline / n.

    To fix this problem, you have to add the input. nextLine () after reading the int as this will consume the / n.

    Therefore, make input. nextLine (); call after input. nextInt (); which reads till end of line.
