In jedis the are using the construct String... keys(this is something new??)

For example this method

jedis.blpop(int timeout, String... keys);

I believe you can use this as both a String as an array. How can I use this in my code(example)?

You could pass an array of strings or a bunch of String objects.

Passing a String[] array.

String sarr[] = {"key1", "key2", "key3"};
jedis.blpop(someTimeout, sarr);

Passing several String objects separately:

jedis.blpop(someTimeout, "key1", "key2", "key3")
