1.	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 Disarium to check if a given number is a disarium number or not. Some of the members of the class are given below: Class name: Disarium Data members/instance variables: int num: stores the number int size: stores the size of the number Methods/Member functions: Disarium (int nn): parameterized constructor to initialize the data members n = nn and size = 0 void countDigit(): counts the total number of digits and assigns it to size int sumofDigits (int n, int p): returns the sum of the digits of the number(n) to the power of their respective positions (p) using recursive technique void check(): checks whether the number is a disarium number and displays the result with an appropriate message Specify the class Disarium giving the details of the constructor! ), void countDigit(), int sumofDigits(int, int) and void check(). Define the mainO function to create an object and call the functions accordingly to enable the task.

Answer»

class Disarium

{

public static void main (String [ ] args) throws IOException

{

BufferedReader br = new BufferedReader (new InputStreamReader)

System.in));

System.out.println ("Enter a number");

int n = Integer.parselnt (br.readLine());

int copy = n, d = 0, sum = 0;

String s = Integer.toString (n);

int len = s.length();

while (copy >0)

{

d = copy % 10;

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

len--; copy = copy/10;

} if (sum == n)

System, outprintln (“Is a disarium no”);

else

System.out.prinln (“Is not a disarium no”);

}
