BASIC JAVA PROGRAMMING

1.  Write a program to add, subtract, multiply and divide 2 numbers .

/* Add 2 numbers */

class Add
{
    public static void main(String args[])
    {
        int a=12;
        int b=6;
        int sum=a+b;
        System.out.println("The sum of two numbers is " +sum);
    }

}

/* Subtract 2 numbers   */
class Subtract
{
    public static void main(String args[])
    {
        int a=12;
        int b=6;
        int sub=a-b;
        System.out.println("The difference of two numbers is " +sub);
    }
}

/* Multiply 2 numbers   */
class Multiply
{
    public static void main(String args[])
    {
        int a=12;
        int b=6;
        int pr=a*b;
        System.out.println("The product of two numbers is " +pr);
    }
}



/*    Divide 2 numbers   */
class Divide
{
    public static void main(String args[])
    {
        int a=12;
        int b=6;
        int div=a/b;
        System.out.println("Dividing 2 numbers we get " +div);
    }
}

2. Write a program to find greatest of 2 numbers

class Greatest

{

    public static void main(String args[])

    {

        int a=5,b=6;

        int greatest = a>b?a:b;

        System.out.println(greatest);

    }

}

3.  Write a program to find the number of 2000,500 and 100 rupee notes from a given denomination

import java.io.*;

class Denomination

{

    public static void main(String args[])

    {

        int a=Integer.parseInt(args[0]);

        int x=a/2000;

        System.out.println("2000* "+x);

        a=a%2000;

        x=a/500;

        System.out.println("500* "+x);

        a=a%500;

        x=a/100;

        System.out.println("100* "+x);

    }

}
