CJ-5 : Four Calculations-Integer no

Type the programs in NOTEPAD or DOS prompt itself, for Consol Application.
Type in NETBEANS or ECLIPSE for Window Application.
Here after , I am just typing the programs only..to know more about it , refer

before doing any JAVA Programs.

***********************************************************************************************

import java.io.*;

class math

{

public static void main(String args[])

{

int a,b,result;

try

{

DataInputStream x=new DataInputStream(System.in);

System.out.println("Enter the first number :");

a=Integer.parseInt(x.readLine());

System.out.println("Enter the second number :");

b=Integer.parseInt(x.readLine());

result=a+b;

System.out.println("Addition = "+result);

result=a-b;

System.out.println("Subtraction = "+result);

result=a*b;

System.out.println("Multiplication = "+result);

result=a/b;

System.out.println("Division = "+result);

}

catch(Exception e)

{

}

}

}

========================================================================= 

Output : 

Enter the first number

8

Enter the second number

4

Addition=12

Subtraction =4

Multiplication =32
