Take in a Java ResultSet the return from a plpgsql function

Question

Here we don't have one select query to take with getString the variables.So how can i take the result from just a return ?

create or replace function takeSomething()
    returns text AS
    $$
BEGIN
    return 'Ok';
END;    
$$ LANGUAGE plpgsql;

Java code:

ResultSet result;
result=Pstatement.executeQuery("Select takeSomething()");
result.next();

Answer 1

ResultSet result;
result=Pstatement.executeQuery("Select takeSomething()");
result.next();
System.out.println(result.getString(1));

as with every other select statement.
