Byte data type is an 8-bit signed two's complement integer
-
Minimum value is -128 (-2^7)
-
Maximum value is 127 (inclusive)(2^7 -1)
-
Default value is 0
-
Byte data type is used to save space in large arrays, mainly in place of integers, since a byte is four times smaller than an integer.
-
Example: byte a = 100, byte b = -50
