pass an array as a function argument

[Matt]

when we pass an array as a function argument, we do this:

printArray(new int[] {4,5,6}); //good

OR

int [] a = {4,5,6};
printArray(a); //good

However, if we declare an array of integers like this, it will yield compile error:
int [] a = new int {1,2,3}; //compile error

what's the rationales? please advise. thanks!!

I think you mean

int[] a = new int[] {1,2,3}; // you forgot the second []
