Class Numeric 1/2/* * [email protected] * javaprogramsbyashking13th.blogspot.in * ashkingjava.blogspot.in *
*
* QUESTION * A class called Numeric has been defined yo find and display the frequency * of each digit present in the number and the product of the digits . * Some of the members of the class are given below : *
* Data Member : n - long integer type *
* Member functions : * Numeric(long a) :constructor to assign a to n * void frequency() :to find the frequency of each digit in the number * int product() :to return the product of the digits of the number *
* Write main() function to implement the above */
import java.io.*;public class Numeric{ long n; public Numeric(long a)//parameterised constructor { n=a; }
void frequency()//method to find frequency of digits { int a[]=new int[10]; //creating an array to store //frequency of digits for(int i=0;i0) { r=(int)(m%10); a[r]=(a[r]+1);//finding frequency /* we declare an array of 10elments i.e.,from index no.0 to 9. * We consider every element to be frequency of the digit equal * to its index no. eg. element at index no. 3 would act as a * variable to store the frequency of the digit 3. * For dong this ,first we extract digits of the given number

Class Numeric (continued) 2/2 * and then we add 10to its counter i.e.,element with the digit * as its index no. */ m=m/10; //updating loop variable } System.out.println("Number entered is "+n); System.out.println("Digit\tfrequency"); for(int j=0;j0) { r=m%10; p=(int)(p*r); m=m/10; } return p; }//end of product
public static void main()throws IOException { DataInputStream d=new DataInputStream(System.in); System.out.println("Enter a number"); long a=Long.parseLong(d.readLine()); Numeric obj1=new Numeric(a); //creating object using //parameterised constructor obj1.frequency();//calling functions int p=obj1.product(); System.out.println("Products of digits of the number is "+p); } //end of main()}
