## Program to find out the sum of Buzz Number between the range from A to B.

import java.util.*;

class Buzz

{

Scanner sc=new Scanner(System.in);

int s=0;

public int sum(int A, int B)

{

for(int i=A;i<=B;i++)

{

if ( i % 10 == 7 || i % 7 == 0 )

{

s=s+i;

}

}

return s;

}

public static void main(String args[ ])

{

Buzz ob = new Buzz();

int buzz_number=ob.sum(4,16);

System.out.println(" sum of Buzz Number="+buzz_number);

}

}

A disarium number is a number in which the sum of the digits to the power of their respective position is equal to the number itself.

Example: 135 = 11 + 32 + 53

Hence, 135 is a disarium number.

## Design a class DisariumNumber to check if a given number is a disarium number or not.

import java.util.*;

public class DisariumNumber

{

public static void main(String[] args)

{

Scanner sc=new Scanner(System.in);

System.out.print("Enter a number (n>0) : ");

int num = sc.nextInt();

// Copy Original Number to temporary variable

int temp = num;

int d = 0;

long sum = 0;

// Convert Number to String to retrieve each digit

String s = String.valueOf(num);

// Retrieve the length of entered number

int len = s.length();

while (temp > 0) {

// extracting the last digit

d = temp % 10;

// Calculate sum

sum = sum +(int) Math.pow(d, len);

len--;

temp = temp/10;

}

if (sum == num) {

System.out

.println("***** " + num + " is a Disarium Number. ******");

}

else {

System.out.println("***** " + num + " is not a Disarium Number. ******");

}

}

}

## Java program to find out the Palindrome Number for N.

import java.util.*;

public class PalindromeNumber

{

public static void main(String[] args)

{

Scanner sc=new Scanner(System.in);

int n, rev = 0, digit;

System.out.println(" Enter the Number to find out the Palindrome Number ");

n=sc.nextInt();

int original=n;

while( n != 0 )

{

digit = n % 10;

rev = rev * 10 + digit;

n =n/10;

}

if (rev == original)

System.out.println(original + " is a palindrome.");

else

System.out.println(original + " is not a palindrome.");

}

}

## Java program to odd and Even Number in N Limit

import java.util.Scanner;

class OddEven

{

public static void main()

{

Scanner sc=new Scanner(System.in);

System.out.println("Enter the limit");

int num= sc.nextInt(); int x;

for(x=0;x<=num;x++)

{

if(x%2==0)

System.out.println("even no.s=" + x );

else

{

System.out.println("odd no.s=" + x );

}

}

}

}

# Check whether the input number is pronic or not??

import java.util.*;

class PronicNumber

{

public static void main(String args[])

{

Scanner sc = new Scanner(System.in);

System.out.print("Enter a number : ");

int n = sc.nextInt();

int k = (int)(Math.sqrt(n));

if(k*(k+1)==n)

System.out.println(n+" is a Pronic Number.");

else

System.out.println(n+" is not a Pronic Number.");

}

}
