# Basic Arithmetic Operators

The basic arithmetic operations-addition,subtraction,multiplication and division-all behave as you would expect for all numeric types.The minus operator also has a unary form that negates its single operand.Remenber that when the division operator is applied to an integer type,there will be no fractional component attached to the  result.

The following simple example program demonstrates the arithamtic operators.It also illustrates the difference between floating-point division and integer division.

//Demonstrate the basic arithmetic operators.

class BasicMath

{

public static void main(String args[])

{

System.out.println(“Integer Arithmatic”);

int a=1+1;

int b=a*3;

int c=b/4;

int d=c-a;

int e=-d;

System.out.println(“a=”+a);

System.out.println(“b=”+b);

System.out.println(“c=”+c);

System.out.println(“d=”+d);

System.out.println(“e=”+e);

//Arithmatic using doubles

System.out.println(“\n Floating point Arithmatic”);

double da=1+1;

double db=da*3;

double dc=db/4;

double dd=dc-a;

double de=-dd;

System.out.println(“da=”+da);

System.out.println(“db=”+db);

System.out.println(“dc=”+dc);

System.out.println(“dd=”+dd);

System.out.println(“de=”+de);

}
