How to overcome type safety warning without ignoring it in eclipse?

I am getting warning from eclipse

Type safety: The expression of type TreeItem[] needs unchecked conversion to conform to TreeItem<AppleItem>[]

while using this:

TreeItem<AppleItem>[] friends = item.getChildren().toArray(new TreeItem[0]);

I dont want to use @uncheck or I dont want to use a loop for inserting one by one. Is there a way to do this?

Appearantly getChildren returns an ArrayList like ArrayList<TreeItem<AppleItem>>

Thanks in advance.

Nope, there's no way to do it without an unchecked cast. @Ivaylo's solution won't save you from casting, either.
