Java program codes: Java - Identifier and primitive datatype in java

In this example you will learn what is identifier and primitive data types of a identifier. This tutorials will teach you how to use these identifier in you  java programming. Identifier is is a simple variable name which is defined as the value container. The type of value stored by identifier is defined by the special java keyword is termed as primitive data type.
In the given example there are some identifiers have been used like byteident, shortident, intident, longident, charident, stringident, floatident, doubleident. And there are some primitive data types of used identifiers have been also used in the program like byte, short, int, long, float, double, char and String. 
All the data type has it's own capacity to keep the maximum value. Which have been mentioned below :

Primitive Data Types

Keyword	Description	Size/Format
Integers
byte	Byte-length integer	8-bit two's complement
short	Short integer	16-bit two's complement
int	Integer	32-bit two's complement
long	Long integer	64-bit two's complement
Real numbers
float	Single-precision floating point	32-bit IEEE 754
double	Double-precision floating point	64-bit IEEE 754
Other types
char	A single character	16-bit Unicode character
boolean	A boolean value (true or false)	true or false
