[9] [10] A conforming program can assume that it can safely store values between −(2 15 −1) [11] and 2 15 −1, [12] but it may not assume that the range is not larger. In Java, a short is always a 16-bit integer. In the Windows API, the datatype SHORT is defined as a 16-bit signed integer on all machines. [7]
Used to finish the execution of a method. It can be followed by a value required by the method definition that is returned to the caller. short The short keyword is used to declare a field that can hold a 16-bit signed two's complement integer. [5] [6] This keyword is also used to declare that a method returns a value of the primitive type ...
The Java virtual machine's set of primitive data types consists of: [12] byte, short, int, long, char (integer types with a variety of ranges) float and double, floating-point numbers with single and double precisions; boolean, a Boolean type with logical values true and false; returnAddress, a value referring to an executable memory address ...
Given a function that accepts an array, a range query (,) on an array = [,..,] takes two indices and and returns the result of when applied to the subarray [, …,].For example, for a function that returns the sum of all values in an array, the range query (,) returns the sum of all values in the range [,].
The resulting information can be used in optimizations such as redundancy elimination, dead code elimination, instruction selection, etc., but can also be used to improve the safety of programs, e.g. in the detection of buffer overruns. [2] Techniques for value range analysis typically use symbolic analysis extensively. [3]

Another meaning of range in computer science is an alternative to iterator. When used in this sense, range is defined as "a pair of begin/end iterators packed together". [ 1 ] It is argued [ 1 ] that "Ranges are a superior abstraction" (compared to iterators) for several reasons, including better safety.
