Make a variable return a random number?
I need to know how to quickly make a variable return a random number, in PHP if i wanted a variable to return a random number it'd look like this using a built in function,
(int)$my_variable = rand(0,10); // returns 0 through 10 randomly
How can i do this with Java if say my variable looks like this.
public Integer madeThisUp = 1; // Needs to be random 0-10 aswell..
I can't find any tutorials on this that make clear sense to me, :-\

1) java.util.Random gives better distribution.
2) java.util.Random has a bunch of methods that correspond directly to common uses of random numbers. I can't imagine a situation where Math.random would be easier to understand.

case in point, when a method is provided for you but you
try to reinvent it with:
int i = (int) (Math.random() * 10);
