Question

I have been working on a project for school. Basically you have to make a script with a couple of scanners. So for instance:

• Return the corresponding ASCII code from a integer, so from a scanner
• Return the surface of a sphere by giving a double.

I now want to make a Scanner class for both functions. But 1 has to be an integer and the second has to be a double. How do I make sure wether the function returns a double or an integer.

I am using the follow code:

public static [Heres what goes wrong] vrager (String type, String tekst) {

Scanner vraag = new Scanner(System.in);

System.out.println(tekst);

type variable = vraag.next();

return variable;

So by calling the function would be like: seconden = (vrager("int", "How many seconds?:));

But if I would like to let the function work for also doubles it goes wrong cause the function is not expecting to return doubles.

How can I solve this issue?

Answer 1

A double can represent every possible int value so return a double.
