In the following code snippet, the program reads input from the console.
However, if the user enters characters instead of the expected data type, will it still work as intended?

Scanner sc = new Scanner(System.in);
System.out.println("Enter number");
int num = sc.nextInt();
System.out.println("number : " + num);
