提问by podunk
How do you get random Doublevalues between 0.0 and 0.06 in Java?
你如何Double在 Java 中获得0.0 和 0.06 之间的随机值？

nextDouble()returns a random floating-point number uniformly distributed between 0 and 1. Simply scale the result as follows:
nextDouble()返回一个在 0 和 1 之间均匀分布的随机浮点数。只需按如下方式缩放结果：
Random generator = new Random();
double number = generator.nextDouble() * .06;
See this documentationfor more examples of Random.

This will give you a random double in the interval [0,0.06):
这将为您提供区间 [0,0.06) 中的随机双倍：
double r = Math.random()*0.06;

To avoid the inexactness of floating point values you can use a double/integer calculation which is more accurate (at least on x86/x64 platforms)
为避免浮点值的不精确性，您可以使用更准确的双精度/整数计算（至少在 x86/x64 平台上）
double d = Math.random() * 6 / 100;

Based on this java doc(though watch the boundary condition):
基于这个java doc（虽然看边界条件）：
new Random().nextDouble() * 0.06
