Putting arrays in ArrayList

Question

Probably a very stupid question, but how can I put an array into an ArrayList?

Example:

String[] strings = {"ex","okay",};
ArrayList<String> stringslist = new ArrayList<String>();

Now how do I put everything in strings, into stringlist?

@christopher Depends on if OP wants an `ArrayList` or `Arrays.ArrayList`, or if they want an `ArrayList — jdphenix, Sep 09 '14 at 19:31

You need to use Arrays.asList() function.

String[] strings = {"ex","okay",};

ArrayList newStringslist = new ArrayList<Element>(Arrays.asList(strings))

You should not use raw types. Also, it would be better to use `List stringList = new ArrayList(Arrays.asList(strings));` because the `List` returned by `Arrays.asList` is not an `ArrayList` and doesn't let you add/remove elements from that list. – Luiggi Mendoza Sep 09 '14 at 19:32

`Arrays.asList` will not return `java.util.ArrayList` but `java.util.Arrays$ArrayList`. – Pshemo Sep 09 '14 at 19:34
