Random.nextFloat不适用于浮点数吗? [英] Random.nextFloat is not applicable for floats?

问题描述

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nextFloat()方法不适用于参数(float)"

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

嗯，什么?

推荐答案

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;
