In memory, an array of string objects must be initialized when the array is declared consists of an array of references to string objects consists of elements, each of which is a reference to a string object is compressed to four bytes for each element

Consists of an array of references to String objects

Explanation:

 In the memory, an array of the string object must consist an array of the reference to the string object. As, an array is the sequence of the given value and these value are must contain the same type in an array. The values in the array is known as elements.  

The string object of an array are basically arranged as the primitive object. The variable of an array consist array reference and it is mainly used when we make variable of an array the it copy the string object reference in the memory.
