Question
Which of the following lines of code would read in a String, and convert it into a whole number?Scanner input = new Scanner(System.in);Int inputRead = input.next();Scanner input = new Scanner(System.in);String inputRead = input.nextLong();Scanner input = new Scanner(System.in);Int inputRead = input.nextInt();Scanner input = new Scanner(System.in);String inputRead = input.nextLine();
Solution
The line of code that reads in a String and converts it into a whole number is:
Scanner input = new Scanner(System.in); Int inputRead = input.nextInt();
This line of code creates a new Scanner object that reads from the standard input stream (System.in). Then it reads the next token from the input as an int. If the next token in the input does not represent an integer value or if it is out of range, it will throw an InputMismatchException.
