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

String intAsString = (String)randomNumber + " " ;

Two things: 1) Don't try to cast randomNumber into a String (remove the (String) part) 2) Remove the space between the quotes - you want to get something like "9", ano not "9 ". So it should just be + "";
