Hi there, For the last question, "Declare a String variable named intAsString. Convert the randomNumber integer to a String value and store it in the intAsString variable. Hint: "Moosh" them together like in the video!"...

First we declare a String:

String

then we name it intAsString:

String intAsString

then we use the equals sign to denote that we are setting that variable to something:

String intAsString =

then we "set it to something", in this case converting randomNumber, an integer, to a String, starting with the data type, Integer...

String intAsString = Integer

then we add a period to call the method "toString" which converts that int to a String:

String intAsString = Integer.toString();

and finally we pass in the parameter of our variable, randomNumber:

String intAsString = Integer.toString(randomNumber);

That last line of code should work. I'm still learning as well, so if someone else reads this and finds a mistake or can suggest a better way to articulate things, please let me know. Thanks!

Hi Peter,

You're close.

The intAsString variable should have a String datatype, not an int

Also, you put a second equal sign which should have been a plus sign. You want to add the number to the empty string so that the number will be converted into a string.

String intAsString = randomNumber + "";

Hi Peter,

Can that method be considered as a best practice ?

Thanks
