Data types in Java programming Hands on coding

 Data Types in JAVA

 In this article, we are going to discuss about data types in java. 

 Data Types;

•  This is the type of data which can be used in the program.
•  There are various predefined data types in the java library like int, char, float etc.

Type of Data Type

Primitive Data Type

• The data type which is predefined in the library is called primitive data type.
• This is named by the keyword, for example int, float, char etc.
• There are eight primitive data types in java.

          Example; byte, short, int, long, float, double, boolean and char.

Integer Type;

Type	Size in bytes	Range
byte	1	-128 to 127
short	2	-32,768 to 32,767
int	4	-2,147,483 to 2,147,483,647
long	8	-9,223,372,036,854,775,808 to 9,223.372,036,854,775,808

 

Float Type;

Keyword	char	Range
syntax	Char x	3.4e-038 to 3.4e+038
value	‘a’, ‘@’, ’9’	1.7e-308 to 1.7e+038

 

 

Boolean;

Keyword	boolean
syntax	boolean x
value	True/False
Range	False

Character;

Keyword	char
syntax	Char x
value	‘a’, ‘@’, ’9’
Range	0 to 65536

 

Non-primitive Data Type;

• The data type which is derived from primitive data type is called non-primitive data type.
• It is also called reference data type.
• These will not store the value, but store a reference to that value.
• Example: Array, class, interface etc.
