Random.nextFloat不适用于花车？

Question

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

Random rand = new Random();

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

"Random类型的方法nextFloat()不适用于参数(float)"

嗯什么？

Answer 1

该nextFloat方法没有参数.调用它,然后在所需范围内缩放返回的值.

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

Random rand = new Random();

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