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.
