Question

I am fairly new to Java and was wondering what the difference between the two is. For this example I used arrays:

class testpile {

public static void main(String[] args)
{
int[] a = {1,2,3,4,5,6}; //First array
int[] b = new int[5];  //Second Array
b[0] = 7;
b[1] = 8;
b[2] = 9;
b[3] = 10;
b[4] = 11;

print(a); 
print(b); 

} 

public static void print(int[] a) {
for (int i = 0; i < a.length; i++)
System.out.print(a[i] + " ");
System.out.println(); 
} 


} 

I understand that using “new” creates a unique object but what are the advantages of using one over the other?

Answer 1

In your example there’s no real difference between the two. The first is mostly just “syntactic sugar” for the latter. In both cases the array is allocated on the heap.
