The byte primitive

suggest change

A byte is a 8-bit signed integer. It can store a minimum value of -27 (-128), and a maximum value of 27 - 1 (127) 

byte example = -36;
byte myByte = 96;
byte anotherByte = 7;

byte addedBytes = (byte) (myByte + anotherByte); // 103
byte subtractedBytes = (byte) (myBytes - anotherByte); // 89

The maximum and minimum values of byte can be found at: 

byte high = Byte.MAX_VALUE;        // high == 127
byte low = Byte.MIN_VALUE;         // low == -128

The default value of a byte is 0 

byte defaultByte;    // defaultByte == 0
