    By reference, array is passed to functions. Or it is passed to original as a pointer. This shows that anything which happens to an array in a function would be affecting the original.

    For understanding an array is passed by reference

    Step 1) In editor, code shall be copied

    Java Code:
    class ArrayDemo {
      
       public static void passByReference(String a[]);
         a[1] = "Changed";

    Array length is not considered as a part of its type therefore an array type’s single variable might possess reference to other array of varying length.

    Given below are few examples ...

    To write an array type use element type name with few empty square bracket pairs[]. Depth of array nesting is indicated by the no. of bracket pairs. Length of array is not its type part.

    An array’s element type might be any type whether reference or primitive. Particularly,

    • Arrays along with an interface type, as the component type are allowed. Such array’s elements might use null reference as their value or any type instances which implements interface.
