Primitive Data Types in Java

Primitive Data Types are predefined by the java language and named by a keyword. There are totally eight Primitive Data Types in Java. Based on the data type of a variable, the operating system allocates memory and decides what can be stored in the reserved memory.
Therefore, by assigning different data types to variables, we can store various data types in these variables.
The following table gives the detail information about Primitive Data Types:

Primitive Data Types (Table)

DataType	Default Value	Size	Type
byte	0	1 byte	Integral Value
short	0	2 byte	Integral Value
int	0	4 byte	Integral Value
long	0L	8 byte	Integral Value
float	0.0f	4 byte	Floating Point
double	0.0d	8 byte	Floating Point
char	'\u0000'	2 byte	Character
boolean	false	1 bit	Boolean

Note: \u0000 means 0 in UNICODE (Universal International Standard Character Encoding)
