Creating a String variable, the intAsString variable??

This one assignment has been haunting me since Saturday, lol.

RandomTest.java 
Random randomGenerator = new Random();
int randomNumber = randomGenerator.nextInt(10);
String intAsString = randomNumber = "";

Hi Thomas,

I pasted the code below in the challenge. It works. Don´t forget to remove the first Random (class name) from the line

Random randomGenerator = new Random();

it shoul look this way:

  Random randomGenerator; //this is already in the challenge
  randomGenerator = new Random();// dont need to declare Random again
  int randomNumber = randomGenerator.nextInt(10);
  String intAsString = Integer.toString(randomNumber);

Hope it helps, let us know if you need more help

Hi Thomas,

you can convert the primitive type int to String.

here is the way you can do it:

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

Integer is a wrapper class that contains methods like toString() that accepts a int variable

Hey Thomas,

thank you so much :) I do the java track for now and if I am fit with it I will focus on android. Java is quite difficult for a programming beginner, but I love to kick my head and try to understand the concepts. Keep on coding ....
