What is an array of objects explain with an example?
The type class array contains the class objects as its individual elements. Thus, a class type array is also referred to as an array of objects.

What is an array of object?
2.7 Arrays of Objects. An array of objects, all of whose elements are of the same class, can be declared just as an array of any built-in type. Each element of the array is an object of that class.

How to Create an ArrayList in Java

What is an array or list quizlet?
