Array instantiation calls a constructor?

Question

When new keyword is encountered in java an object is created and a constructor is called.

So which constructor is called when an array object is created.

Eg int[] a = new int[];

We know that array are Objects.

Answer 1

Arrays don't use contructors to initialize. If you try to compile int[] array = new int[10]; you would get something like the below bytecode:

bipush 10
newarray int
astore_1

On the other hand, the bytecode instructions for Person p = new Person(); would look like the below (notice the call to new and init denoting the call to the constructor):

new test/Person
dup
invokespecial test/Person/<init>()V
astore_2

Hence arrays have their own way of creation in the JVM that is different than creating class objects.
