Array declaration in Java

Difference between int[] array and int array[]

Is int[] arr; functionally the same as int arr[];?

i feel int arr[] is worse: int[] arr follows TYPE VAR_NAME style, whereas int arr[] is more like TY VAR_NAME PE — iluxa, Mar 03 '11 at 20:23
I find it amusing that what could easily have been written as a subjective question (which is better?) wasn't, and then it gets subjective answers and comments. — Isaac Truett, Mar 03 '11 at 20:28

Yes. You can put the braces in either place when declaring an array.

Bonus: you can even put 'em here: int []arr

Yes, the functionality is the same. You can have the braces anywhere.

int[] a,b,c[];

is equivalent to

int a[],b[],c[][];

I hope you don't really write int[] c[]; in your own code! – Neil Mar 03 '11 at 20:45
Yea, sure I wont. It's just to show the possibility and semantics. – dev_musings Mar 03 '11 at 21:00

It's just the matter of style. You can pick the style you like. They perform exactly the same. Some claim that if you write "int[] array", it will be clearer that it's an array of integer rather than writing "int array[]".

It is, it's just to appease C++ developers they include int arr[]. (Or at least what I told in school)

Yes it's the same. int[] arr is more convenient though.
