Which of the following is NOT an example of an integral data type?

The correct answer is that "Double" is not an example of an integral data type. Integral data types are those that represent whole numbers without any fractional component. They are used to store numeric values that do not require a decimal point.

The Byte, Short, and Long types are all integral data types. They differ in the size of the number they can store and thus can represent different ranges of integer values. For example, a Byte can store values from 0 to 255, while a Long can represent a much larger range of numbers.

In contrast, the Double type is a floating-point data type, which means it is designed to represent numbers that can have decimal points. This allows for a much broader range of values, including fractions. Therefore, while integral types are specifically focused on whole numbers, the Double type caters to a wider array of numeric representations, including those that require decimal precision.
