3. ARITHMETIC OPERATORS

Welcome back to my third java tutorial.In last tutorial we are learning to run a program.Before that we have to know that why are we learning java.Whats make java one of the best programming language.Here are they.............
1.Simple
2.Secure
3.Portable
4.Object-oriented
5.Robust
6.Multithreaded
7.Architecture-neutral
8.Interpreted
9.High performance
10.Distributed
11.Dynamic

 Today we will learning arithmetic operators.
First of all we have to remember 

Name	Width	Range
int	32	-2,147,483,648 to 2,147,483,647
double	64	4.9e-324 to 1.8e+308
float	32	1.4e-045 to 3.4e+038
string		String

arithmetic operators

=	Assign value
==	equal
!=	Not equal
<	Less than
>	Greater than
<=	Less or equal
>=	Greater or equal
+	Addition
-	Subtraction
*	Multiplication
/	division
%	modulus
&&	and
||	or

now a simple program

create a class (I have named pavel);
(last tutorial i have seen you how to create a class.So i hope you can)


public class pavel {
      public static void main(String args[]){
     int sub,multi,div,add,mod;
     int i=8;
     int j=2;
     
     //now addition
     add=i+j;
      System.out.println("Subtraction of numbers : "+ add);
     //now Subtraction
     sub=i-j;
     System.out.println("Subtraction of numbers : "+ sub);
     //now Multiplication
     multi=i*j;
     System.out.println("Multiplication of numbers : "+ multi);
     //now division
     div=i/j;
     System.out.println("division of numbers : "+ div);
     //now modulus
     mod=i%j;
     System.out.println("modulus of numbers : "+ mod);
      }
}
result of the program is

Addition of numbers : 10
Subtraction of numbers : 6
Multiplication of numbers : 16
division of numbers : 4
modulus of numbers : 0

Here see we take 7 integer variable.initialized two variable i=8 and j=2;
here //(two backslash means that's a comment .it is not executed  )
add=i+j;
First we add i and j means (8+2) so it's result is 10.
System.out.println("Subtraction of numbers : "+ add);
Here in println we use '+' for adding .
sub=i-j;
secondly we subtract i and j (8-2) so result is 6
multi=i*j;
here we multiply i and j(8*2)so result is 16
div=i/j;
here we divided i with j(8/2)so result is 4
 mod=i%j;
here we modulus i with j(8%2)but 8 is divisible by 2. so result is 0
but if     i=9 and j=2
then     mod=i%j ;     equal 1.
or
    i=11 and j=3
then
    mod=i%j;             equal 2;

next tutorial we we learning more arithmetic operation with if-else statement.
Till then best of luck.
