Short

The short primitive datatype is another less commonly used integer-related datatype due to its limited range of -32,768 to 32,767. Let's glance at the example below showing the declaration and use of short.

package exlcode;

public class ShortDataTypeExample {

  // short can be any integer between -32768 and 32767
  public static short exampleVariableOne = 100;
  public static short exampleVariableTwo = -100;
  public static short exampleVariableThree = 0;

  public static void main(String[] args) {
    System.out.println(exampleVariableOne);
    System.out.println(exampleVariableTwo);
    System.out.println(exampleVariableThree);
  }
}

short functions similarly to int as it can only hold whole, non-decimal numbers. This datatype was commonly used when 16-bit computers were used, and are rarely used now as int has pretty much taken its place. However, short takes up about half the space of an int, so in a specific case when you are dealing with a large list of whole numbers, you may chose to use short to save space. With that being said, we will just use int for most of our programs.
