array

[Raju Champaklal]

why cant i assign an int array to an Integer array?

[Phungsuk Wangdu]

beacause the int cant be automatically boxed to Integer
whereas an Integer can be autoboxed to int automatically


well i may be wrong also just giving a try

[Neha Daga]

write a code and you will find the answer. If you are unable to understand after that, then I will tell you.
hint: arrays are object

  class Zippy {
    public static void main(String g[]){
int[] a={1,2,3};
float[] b={1,2,3};//but this compiles?
float[] c=a;//doesnt compile?
Integer[] i=a;//doesnt compile

 }
}

OOK i guess i am unable to understand please give us the reason

Here is a bit more of a hint: Arrays are objects. Integer is an object. Can you cast an Array to an Integer?

[Raju Champaklal]

nope because they arent in the same hierarchy..but so what? and what about float[] f=a? even this doesnt compile..why

[Phungsuk Wangdu]

well i got it now

[Raju Champaklal]

explain it to me Mahesh

[Raju Champaklal]

is it because int[] and Integer[] arent in the same hierrachy?

[Phungsuk Wangdu]

well just open your k&b and start reading page no 233 you will understand it
Its really easy

[Neha Daga]

you cant cast an array object that contains an int to an array object that contains float. think it is written in K&B you can add a short to an array of ints but can assign an array of short to an array of ints. I leave the reason for you to find it then I know you will understand it.

time nahi he samjhne ka

[Neha Daga]

ok then just remember that array of one primitive type cant be assigned to array of another primitive type
and you can put short byte char and int in an array of int.
and about the wrapper array i think you got that

If I remember, I told you before to not use Hindi on javaranch. People from all around the world visit javaranch, so please restrict yourself to using English...
