In an array declaration, this indicates the number of elements that the array will have.

a. subscript
b. size declarator
c. element sum
d. reference variable

Expert Solution & Answer

Program Description Answer

In an array declaration, “size declarator” indicates the number of elements that the array will have.

Hence, the correct answer is option “B”.

Explanation of Solution

Size declarator:

In an array the “size declarator” must be a non-negative integer expression. It may be a variable or a literal value. It is a common practice to use a final variable as a size declarator.

Example:

final int NUM_ELEMENTS = 6;

int[] numbers = new int[NUM_ELEMENTS];

Explanation for wrong answers:

a.Subscript:

A “subscript” is used as an index to pinpoint a specific element within an array.

Hence, the option “A” is wrong.

c.element sum:

The “element sum” is used to add the numbers of element in an array.

Hence, the option “C” is wrong.

d.Reference variable:

The user declare a “reference variable” and use the new keyword to create an instance of the array in memory. The reference variable can be declared as follows:

numbers = new int[6];

Hence, the option “D” is wrong.
