type in java code example

Example 1: all data types in java

Data Type	Size	Stores
byte		1 byte	whole numbers from -128 to 127
short		2 bytes	whole numbers from -32,768 to 32,767
int			4 bytes	whole numbers from -2,147,483,648 to 2,147,483,647
long		8 bytes	whole numbers from -9,223,372,036,854,775,808 to 9,223,372,036,854,775,807
float		4 bytes	fractional numbers; sufficient for storing 6 to 7 decimal digits
double		8 bytes	fractional numbers; sufficient for storing 15 decimal digits
boolean		1 bit	true or false values
char		2 bytes	single character/letter or ASCII values

Example 2: primitive and non primitive data types in java

Primitive data types are those data types which are used by programmers when creating variables in their program. 
For example :-
    * boolean
    * char
    * byte
    * short
    * int
    * long
    * float
    * double
Non-Primitive data types:
    * String
    * array
    * enum
    * class
    * etc

Example 3: java typeof

Object obj = null;
obj = new ArrayList<String>();
System.out.println(obj.getClass());

obj = "dummy";
System.out.println(obj.getClass());

obj = 4;
System.out.println(obj.getClass());

Example 4: what is primitive data type in java

Primitive types are the most basic data types available within the Java language. There are 8: boolean , byte , char , short , int , long , float and double . These types serve as the building blocks of data manipulation in Java. Such types serve only one purpose — containing pure, simple values of a kind.

Primitive types are the most basic data
types available within the Java language. 
Some of them are boolean , byte , char ,
short , int , long , float and double . 
These types serve as the building blocks
of data manipulation in Java.
