Primitive Data Types in Java Programming are similar  to c and c++.they include byte,int ,short,long,Boolean, char, float and double.

A variables data type determines the value it contain and the operation occurs on it.A variables data type determines the value it contain and the operation occurs on it.

Byte it takes 1 byte size and covers values from -128 to 127

int it takes 4 bytes and cast into numeric values only.it covers values from -2,147,483,648 to 2,147,483,647

Short it takes 2 bytes. it also cast into numeric values. it covers values from  -32,768 to 32,767

long it takes 8 bytes it cast into numeric values.

Boolean  it takes 1 byte ,it take values true and false only

char  it takes 2 bytes, unsigned, Unicode, 0 to 65,535 

float it takes 4 bytes ,it cast into decimal or fractional values

double it takes eight 8 bytes and cast into decimal values

 
boolean result = true;
     char capitalB = 'B';
     byte b = 110; 
     short s = 100; 
     int i = 500;
