Random.nextFloat is not applicable for floats?

Question

float minX = 50.0f;
float maxX = 100.0f;

Random rand = new Random();

float finalX = rand.nextFloat(maxX - minX + 1.0f) + minX;

"The method nextFloat() in the type Random is not applicable for the arguments (float)"

Um, what?

Answer 1

The nextFloat method doesn't take an argument. Call it, then scale the returned value over the range you want.

float minX = 50.0f;
float maxX = 100.0f;

Random rand = new Random();

float finalX = rand.nextFloat() * (maxX - minX) + minX;
