How do I convert a String[] object to a Set?

[RPFeltz]

I want to store a String.split("seperator") to a Set<String>.
Example:

Set<String> = (Set<String>) "a|b|c".split("|");

Sadly String[] and Set are incompatible types.
About the same as using .add three times, but shorter.
Any way to do this?

Any collection has a constructor which takes as an argument another collection. Try seeing if you can find something which turns an array into a list, and pass it into a sets constrctor.

Found something that turns an array to a list.
Set<String> YesNo = (Set<String>) Arrays.asList("y|yes|n|no|-ignoreCase".split("|"));
Thanks.

Set<String> YesNo = (Set<String>) Arrays.asList("y|yes|n|no|-ignoreCase".split("|"));

Are you sure that you want to cast a List<String> into a Set<String>? Does that even compile?

Edit: it in fact does compile, but if run will throw the expected ClassCastException. Original poster: use the Set constructor as has already been recommended. Since Set is an interface, you'll need to use one of its concrete children such as HashSet. Also, there's danger when splitting on "|" because split uses a regular expression String and | has special meaning in regex. Better to escape it:

i.e.,

Set<String> YesNo = new HashSet<String>(Arrays.asList("y|yes|n|no|-ignoreCase".split("\\|")));
