b) ClassName[] arrayName = new ClassName[size];

d) ClassName[] arrayName;

Answer 1

The correct way to declare an array of object references in Java is with the syntax ClassName[] arrayName = new ClassName[size].

Step-by-step explanation:

The correct way to declare an array of object references in Java is option b) ClassName[] arrayName = new ClassName[size];

For example, if you have a class named Student, and you want to create an array of object references to store multiple student objects, you would declare it like this:

Student[] studentArray = new Student[5];

This creates an array of object references to hold 5 Student objects. Each element in the array can store a reference to a Student object.
