After knowing the Java rules of Data Type Casting (Type Conversion), let us cast byte to short. The byte takes 1 byte of memory and short takes two bytes of memory. Assignment 1 byte value to 2 bytes is done implicitly by the JVM.
byte –> short –> int –> long –> float –> double
The left-side value can be assigned to any right-side value and is done implicitly. The reverse requires explicit casting.
Examples:
short x = 10;
int y = x;
byte x = 10;
short y = x;
Following example on byte to short illustrates the syntax of automatic promotion of widening conversion of Java.
public class Conversions
{
public static void main(String args[])
{
byte b1 = 10; // 1 byte
short s1 = b1; // one byte to 2 bytes
System.out.println("byte value: " + b1); // prints 10
System.out.println("Converted short value: " + s1); // prints 10
}
}
Output screenshot of byte to short Java
1 byte value b1 is assigned to 2 bytes s1 and is type casted implicitly.
