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.
