java - Need " " when concatenating strings? -


in code below (return statement on last line), need " " between variable firstname , middleinitial? long 1 variable string, doesn't concatenate else string when linked + ?

so example, work?
return firstname + middleinitial + lastname
if not, why not? 

 // name object represents name such "john q. public".  public class name {      string firstname;      char middleinitial;      string lastname;       // name in normal order such "john q. public".      public string getnormalorder() {          return firstname + " " + middleinitial + ". " + lastname; }

the " " necessary if want space between firstname , middleinitial. if don't want space, can omit it.
