Primitive Types
Integral Primitive Type
There are five integral primitive types in Java: byte, short, int, long and char. Of those, the first four (byte, short, int and long) are signed, and char is unsigned.
byte is the smallest integral data type available in Java. Its values used one-byte (8 bites) and they are represented in two's complement.
Floating Point Primitive Type
Literals
There are no byte literals, but any int literal that falls within the range of a byte can be assigned to a byte variable.
