Quizplus · Accepted Answer

The correct method to use before calling nextInt() is hasNextInt(). This method returns true if the next token in the input stream is a valid integer, and false otherwise. This will help ensure that a NumberFormatException is not thrown when trying to read in the input as an integer. The other options listed (A, B, D) are not valid methods and would result in a compilation error.
