Java Program To Perform Arithmetic Operations

How to write a java program to perform arithmetic operation, In this java program use different arithmetic operators as like addition, subtraction, multiplication, division and Reminder.In this java program write in following ways.

Three ways to perform arithmetic operation:

• Without user input
• With user input at runtime
• With user input at command line

Arithmetic operation without user input:

It means at the time of declaration of variable, value is assign on a and b variable. ‘a’ is an one variable and ‘b’ is another variable. ‘arithmetic’ is a class name.

class arithmetic
 {
  public static void main (String args [] )
   {
    int a=15, b=12; 
    System.out.println("Addition of a and b = "+(a+b));
    System.out.println("Subtraction of a and b = "+(a-b));
    System.out.println("Multiplication of and b = "+(m*n));
    System.out.println("Division of a and b = "+(m/n));
    System.out.println("Remainder of a and b= "+(m%n));
   }
 }

Output:

Addition of a and b = 27
Subtraction of a and b = 3
Multiplication of and b = 180
Division of a and b = 1
Remainder of a and b= 3

Arithmetic operation with user input at run time:

It means at the execution time the value is assign on a and b variable.

import java.util.*;
class arithmetic
 {
  public static void main (String args [])
  {
   int a,b;
   Scanner sc= new Scanner(System.in);
   System.out.print("Enter two no a and b is :");
   a=sc.nextInt();
   b=sc.nextInt();
   System.out.println("Addition of a and b ="+(a+b));
   System.out.println("Subtraction of a and b ="+(a-b));
   System.out.println("Multiplication of and b ="+(a*b));
   System.out.println("Division of a and b ="+(a/b));
   System.out.println("Remainder of a and b="+(a%b));
  }
 }

Output:

Enter two no a and b is : 20 15
Addition of a and b = 35
Subtraction of a and b = 5
Multiplication of and b = 300
Division of a and b = 1
Remainder of a and b= 5

Arithmetic operation with user input at command line :

It means the value is assign on a and b variable at the command line.

class arithmetic
{
 public static void main (String args [])
  {
   int a,b;a=Integer.parseInt(args[0]);
   b=Integer.parseInt(args[1]);
   System.out.println("Addition of a and b ="+(a+b))
   System.out.println("Subtraction of a and b ="+(a-b));
   System.out.println("Multiplication of and b ="+(a*b));
   System.out.println("Division of a and b ="+(a/b));
   System.out.println("Remainder of a and b="+(a%b));
  }
}

Output:

c:\>java arithmetic 30 25
Addition of a and b = 55
Subtraction of a and b = 5
Multiplication of and b = 750
Division of a and b = 1
Remainder of a and b= 5
