array declaration

[Yosi Hendarsjah]

What's the difference between these two methods of array declarations?

  
int[] a1 = new int[]{2,6,9};
int[] a2 = {2,6,9};

hi yoshi
the first stmt is anonymous array.We can use such array construction if we want to send an array as an argument to some method.

void method1(int[] a)
{
 }
void someothermethod()
{
  method1(new int[]{1,2,3});
}

int[] a1 = new int[]{2,6,9};
int[] a2 = {2,6,9};
Hi,
{} is considered as array intiallizer.In the second way of initiallization when compilers finds the '{}' then it searches the data types.Since the left hand mention it an int. a2 is intiallized with the int types.
But in the first the data type is explicitly mentioned as int. I hope that it will help u a little.
Thanks.

Are the bytecodes the same or different?

[Harvinder Singh]

Hi Yoshi,
The bytecode are converted to machine specific code by JVM which is one of the way by which java achieve platform independency.Urs suggestion are always invited.
Thanks.
