replacing null declaration with Optional java -


i'm having hard time understanding of optional class. so, have task need replace every null initialization optional class.

e.g.

i have class client

so made object this:

client chosen = null;

how supposed replace null initialization optional?

your initialization following:

optional<client> chosen = optional.empty();

or if want assign initial value:

client client = new client(); optional<client> chosen = optional.of(client);
