DataEnum allows you to work withalgebraic data typesin Java. You can think of it as an enum where every individual value can have different data associated with it. What problem does it solve? The idea of algebraic data types is not new and already exists in many other programming languages...
The eight primitive data types supported by the Java programming language are: byte: The byte data type is an 8-bit signed two's complement integer. It has a minimum value of -128 and a maximum value of 127 (inclusive). The byte data type can be useful for saving memory in large ...
