I think this should work. I am not sure if the second "" is needed there.
?
1
String secret = "" + getRandomNumber(1,9) + "" + getRandomNumber(1,9);

No, it is not needed. The first set is to tell the compiler that you are creating/building a String object; and you are continuing to build the same object with the second random number.

That is not what is happening here. We are taking numeric values and adding their digital characters to a string. However, there are several good reasons why one might want to convert a numeric string into a number. This is often done when a numeric value is input as a string or read as a string from file data.
