Generate a random double between 0.0 and 1.0, multiply by the number of int values you want to choose from, add the smallest int value you want, round it down to the nearest integer using Math.floor(), and cast the result to an int. For example, the following class simulates a six-sided die by producing random, uniformly distributed ints between 1 and 6.

To run a program you've written, eg in JAVA, it must first be translated into machine code so the computer can read it. This is what compilers and interpreters do.

However, compilers convert the code all at once, save it, then run it; whereas interpreters translate the code one line at a time, as it is run.


Interpreters tend to result in faster translating of code so they are used mostly for debugging. This is because if you used a compiler, you'd have to re-compile your entire project every time you changed one little thing.

However, it's not very efficient to keep re-translating your code once you've finished writing it, because it would waste CPU time. Because of this, once code is done, it is normally compiled so that it runs faster and takes up less space. Another advantage of this is that your code is then much harder to copy without lengthy 'reverse engineering.'
