Java Data Types
There 2 Types Of Data Types In Java
1) Primitive -> byte, char, short, int, long, float, double and boolean.
2) Non-primitive -> (All Classes) -> String, Arrays etc.
Type Size Stores
byte 1 byte whole numbers from -128 to 127
short 2 bytes "" -32,768 to 32,767
int 4 bytes "" -2,147,483,648 to 2,147,483,647
long 8 bytes ""-9,223,372,036,854,775,808 to 9,223,372,036,854,775,807
float 4 bytes fractional numbers; for storing 6 to 7 decimal digits
double 8 bytes fractional numbers; "" 15 ""
boolean 1 bit true or false values
char 2 bytes single character/letter or ASCII values

Example 2: 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.
