如何将普通的双精度数组转换为番石榴不可变数组

Question

I was just wondering how would i go about converting this:

Into a Google Guava ImmutableDoubleArray.

public class Data  {

    private final ImmutableDoubleArray arrays;

    public Data(double[] array)
    {

    }

Thank you.

Answer 1

this.arrays = ImmutableDoubleArray.copyOf(array);

Using ImmutableDoubleArray is generally preferable to using ImmutableList , because it does not come with the overhead of boxing.
