Arrays in Java are also objects. They need to be declared and then created. In order to declare a variable that will hold an array of integers, we use the following syntax:

int[] arr;

Notice there is no size, since we didn't create the array yet.

arr = new int[10];

This will create a new array with the size of 10. We can check the size by printing the array's length:

System.out.println(arr.length);
