What method instead of using Java like. NET the ref and out

NET as there is in the method of judging a user is not, in the words returned his phone number
I can define methods
boolean GetUserPhone (string username, out string phone);
Call
string phone;
boolean has = GetUserPhone ("Jerry", out phone);
Console.Write ("the existence =" + has.ToString ());
Console.Write ("phone number =" + phone);
-------------------------------------------------- -
But I found the time to write Java code Java No out this function
That should be how to achieve my Java right above request?

Package a class, the need to return the contents into them.
If

 
public class PhoneInfo {
Boolean isExists; 
String Phone; 
} 

PhoneInfo GetUserPhone (string username) {
... 
}

This is too much trouble, right?
When I only want to return, there are two return values ​​have a class package

It can only use one floor of the method, java on virtue, original design parameters considered pass-by-reference increases the complexity of the language, did not design this feature
