Question

I have an iPhone version of my application which is using a bit of code for setting up colors.

((rand() % 176) * 80) / 256.0f

I am new to objective c so I can’t figure out how this is working. I want to make exact copy of this for Android in Java.

In Java we usually use Random() . How am i suppose to implement this above function using Random r = Random();

Answer 1

Equivalent one-liner in Java would be:

((new Random().nextInt() % 176) * 80) / 256.0f;

More about the random class on the JavaDoc

Obviously you should not create a new instance of Random each time.

Random r = new Random();
// call r.nextInt() each time you need a new random integer
double color = ((r.nextInt() % 176) * 80) / 256.0f;
