• is array object in java 8 answers

how come can assign array object reference

object x = (object) new int[] { 1, 2, 3 };// no error object y = new int[] { 1, 2, 3 };//no error 

do java arrays inherit object similar classes?

i expected give me compile time error.

doing this:

system.out.println(x.tostring() + " " + x.getclass().getname() + " " + x.getclass().gettypename()); 

results in:

[i@15db9742 [i int[] 

do java arrays inherit object similar classes?

yes, because arrays instances of classes, other objects. why have hashcode , tostring , getclass, inherit them object.

from jls§10.1:

the supertype relation array types not same superclass relation. direct supertype of integer[] number[] according §4.10.3, direct superclass of integer[] object according class object integer[] (§10.8). not matter in practice, because object supertype of array types.

(my emphasis)

and (perhaps relevant) jls§10.2:

a variable of array type holds reference object.
