An integral data type is a data type whose values are integers. There are five integral primitive types in Java: [[Java_Language#byte|byte]], [[Java_Language#short|short]], [[Java_Language#int|int]], [[Java_Language#long|long]] and [[Java_Language#char|char]]. Of those, the first four (<code>byte</code>, <code>short</code>, <code>int</code> and <code>long</code>) are signed, and <code>char</code> is unsigned.
 
<code>byte</code> is the smallest integral data type available in Java. Its values used one-byte (8 bites) and they are represented in two's complement.

There are no <code>byte</code> literals, but any <code>int</code> literal that falls within the range of a byte can be assigned to a byte variable.
