Question

Hello,

What is the answer to this Java question?

After​ ​the​ ​following​ ​declaration:​ ​​People[]​ ​crowd​ ​=​ ​new​ ​People[10]; What​ ​is​ ​the​ ​value​ ​of​ ​​crowd[0]​?
a) Undefined

b) The​ ​address​ ​of​ ​a​ ​People​ ​object

c) The​ ​address​ ​of​ ​a​ ​crowd​ ​object

d) null

e) Select​ ​this​ ​option​ ​if​ ​you​ ​think​ ​​crowd[0]​ ​​has​ ​invalid​ ​syntax

Answer 1

The answer would be option d : null.

As crowd is not intialized to any value, the value of crowd[0] will be null

1 public class People 2 { 3 public static void main(String[] args) { 4 5 People[] crowd =new People[10]; 6 System.out.println(crowd[0]); 7 8 9 } }

OUTPUT null
