[Java] What class or method might be used for asking the user to enter a value?

The Scanner class can ask for a parameter but, what if I want a personalized message asking for a particular kind of data?

You can use one Scanner for all the differents types. Scanner input = new Scanner(System.in); input.nextLine(); input.nextInt(); input.nextDouble(); input.next().charAt(0); input.nextBoolean()

you assign your type as you see fit and call the scanner to look for it.. Scanner strIn = new Scanner(System.in); String name=strIn.nextLine(); Scanner intIn = new Scanner(System.in); int number=input.nextInt(); I did read it is bad to use a scanner for one type after using it for another type so I generally make a scanner for each type be it a string or an integer
