Chance GAME confuse.....
I'm a first year student and I'm confuse about how to do this I don't know where to plug in the random number or where to use it........

"Goal : Hand-in your code with a goal of 30, but design the program so that the goal can be updated easily.



Random Numbers: Use this code to get the computer to generate a random int >=1 and <= 10:



r = (int) (Math.random () * 10)+1;



Input and Output: After each move, the program should output a line (using System.out.println) which says either:

1) "Good pick! You moved ahead " + x + " spaces. Currently you are at " + location.” or

2) "Oops! You moved back " + … + " spaces. Currently you are at " + location.” or

3) "Net result of nothing! You are still at " + location.”
