Array initialisation in java

Question

I noticed one could write code like this, which is perfectly normal, by the way:

int arrays[] = {1, 2, 3};
for (int n : arrays)
   System.out.println(n);
         


        

Answer 1

Because arrays are objects, and have to be instantiated. Java does not recognize {} by itself as an array. It does, however, permit you to use a code block (i.e. code in {..}) to define the initial elements of the array.

The way you accomplish this is described by the answer above.
