array to list# Java - 爪哇娇娃

1 楼
Hi I have a stupid question: how to convert an array to a list?
For example, I want to convert double [] a = {1.0, 2.0}; to a type of List<
Double>.
How to do it without using a loop to visit every element in the array?
I tried Arrays.asList but got an "incompatible type" error message.
Thanks

Double [] a = {1.0,2.0}; should fix it.

If you have to convert from a primitive array, there's no way other than
loop it.

right, I second Foxman. You just need to loop and copy each reference out to
the list.
