Regarding array declaration

[Pradeep Kumar]

What is the differnece between the below two declarations.
As results of both the statements are the same.Apart from that are there any other differences.


int[] aray1 = {1,2,3,4,5,5};
int[] aray2 =new int[]{1,2,3,4};

I think that using the second method is the best usually.

[gang meng]

The first method delcares a primitive date type of array.That is a original array.
The second method declares a array of object.

Certainly,there are differences.
Do you know the differences from heap and stack?
Array is an Object. When you declared an Object,the computer will create a space in the heap of memory and create a quote in the stack of memory. When you new an Object,the computer so do.

In my opinion,
int[] aray1 = {1,2,3,4,5,5};
The statement will create one space and one quote.

int[] aray2 =new int[]{1,2,3,4};
The statement will create two space and one quote.

The only difference is that the first version can only be used on the same line as the declaration.

Consider:

int[] array1 = {1, 2, 3, 4};     // legal
int[] array2 = new int[] {1, 2, 3, 4}; // legal
array1 = {5, 6, 7, 8};                 // ILLEGAL! no declaration
array2 = new int[] {5, 6, 7, 8};       // legal
doSomething({1, 2, 3, 4});             // ILLEGAL! no declaration
doSomething(new int[] {1, 2, 3, 4});   // legal

Please don't ask the same question twice.
