Does the readLine method only return String data?

So, I typed 333 as my input when the readLine method was called and it worked, why? (Even though the returned value was stored in a String variable)

Yes, the readLine() method only returns a String value. So typing 333 as the input on the readLine is equivalent to setting a variable to "333" in your Java code. If you needed to get the integer datatype from the readLine method, you would first need to return a String value and then convert it to an integer using parseInt(), like so:

String input = console.readLine("Enter input");
int inputToInt = Integer.parseInt(input);
// inputToInt now equals 333 instead of "333"

Hope that helps
