short to byte Java

short to byte Java


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

The byte takes 1 byte of memory and short takes 2 bytes of memory. Assigning 2 bytes of memory to 1 byte of memory requires explicit casting. This is known as narrowing conversion.

See the order of data types to know the 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 short to byte requires explicit casting.

Examples of implicit casting

short x = 10;
int y = x;

byte x = 10;
short y = x;

Following program explains explicit casting, Java style where a short is assigned to byte.

byte b1 = s1;

The above statement raises a compilation error "possible loss of precision".

byte b1 = (byte) s1;

The short s1 is explicitly type casted to byte b1. Observe, the syntax of explicit casting. On both sides, it should be byte.
