Help please D:

What am i doing wrong in this test

Declare a String variable named intAsString. Convert the randomNumber integer to a String value and store it in the intAsString variable. Hint: Use the toString() method of the Integer class

Random randomGenerator = new Random (); int randomNumber = randomGenerator.nextInt(10); String = "intAsString"; Integer.toString(intAsString);

String = "intAsString"; 

This is an invalid Java statement

Lets take a closer look

In the first line String keyword is not followed by a variable name, which is an error. By convention in java we always have datatype variable_name , where datatype could be int, float, String etc.

In the second line, the toString method takes an integer value and not a String value. If you come to think about it, if something is already string why would you convert it to string all over again.

Here is a quick look at fixing the errors

Random randomGenerator = new Random ();
int randomNumber = randomGenerator.nextInt(10);
String intAsString = Integer.toString(randomNumber); //pass the int variable as parameter

Hope that helps

Could you please post your questions a bit more clearly? I am not able to understand what is your issue.

You have a mistake in your String declaration... It should be

String intAsString = Integer.toString(randomNumber);

Glad I could help. See you around!
