short to double Java

After knowing primitive data types and Java rules of Data Type Casting (Type Conversion), let us cast short to double as an example.

The short takes 2 byte of memory and double takes 8 bytes of memory. Assignment 2 bytes of memory to 8 byte of memory is done by JVM implicitly and is known as widening conversion.

See the data types order to know the brief rules of casting.

byte –> short –> int –> long –> float –> double

The left-side value can be assigned to any right-side value and is done implicitly. The reverse like int to short requires explicit casting.

Examples of implicit casting

short x = 10;
int y = x;

byte x = 10;
short y = x;

Following program on short to double explains the Java syntax of implict casting where a short value is assigned to a double value.

public class Conversions
  public static void main(String args[])
    short s1 = 10;              // 2 bytes
    double d1 = s1;             // 2 bytes assigned to 8 bytes

    System.out.println("short value: " + s1);                // prints 10
    System.out.println("Converted double value: " + d1);     // prints 10.0

double d1 = s1;

The short s1 is assigned to double d1. This is done automatically by JVM.
