java中的空浮点数组(Null float array in java)

java中的空浮点数组(Null float array in java)

我试图用nulls和NaNs创建一个float数组：

float[] fArray = {null, null};

要么

float[] fArray = {float.NaN, float.NaN};

在java中有可能做这样的事情吗？

I've tried to create a float array with nulls and NaNs:

float[] fArray = {null, null};

or

float[] fArray = {float.NaN, float.NaN};

Is it possible in java to do something like this?

float是基本类型，不能为null 。 有一个包装类Float （注意大写）可以为null 。 NaN也是Float的float成员。 看看Float的文档 。

float is a primitive type and can not be null. There is a wrapper class Float (note the capital) that can be null. Also NaN is a member of Float not of float. Have a look at the documentation of Float.
