5 Questions
What is a data type and what does it define?
A data type defines a collection of data objects and a set of predefined operations on those objects. It is a descriptor that represents the attributes of a variable and an instance of a user-defined (abstract data) type.
What are primitive data types and how are they defined?
Primitive data types are those not defined in terms of other data types. They are almost always an exact reflection of the hardware, with some being merely reflections of the hardware and others requiring little non-hardware support.
How many different integer types may exist in a language, and what are examples of Java's signed integer sizes?
There may be as many as eight different integer types in a language. Java's signed integer sizes include byte, short, int, and long.
What do floating point data types model, and how are they supported in languages for scientific use?
Floating point data types model real numbers, but only as approximations. Languages for scientific use support at least two floating-point types.
What is the main design issue for all data types, and what does it involve?
One design issue for all data types is determining what operations are defined and how they are specified. This involves specifying the predefined operations on the data objects defined by the data type.
