In this post, we will learn Repetition of a Number Program in java Programming language.
Question:
Pinky’s mom provides Pinky with a number and a key digit. She wants Pinky to find out how many times that key digit appears in that number. Help Pinky to do that by writing a program.
Sample Input 1:
Enter the number 16466
Enter the key digit 6
Sample Output 1:
6 appears 3 times in 16466
Sample Input 2:
Enter the number 8458
Enter the key digit 6
Sample Output 2:
6 appears 0 times in 8458
Repetition of a Number Program in java CODE:–
import java.util.Scanner;
public class NumberRepetition
{
public static void main (String[] args) {
int num,key,times,r,flag=0;
Scanner sc=new Scanner(System.in);
System.out.println("Enter the number ");
num=sc.nextInt();
System.out.println("Enter the key digit ");
key=sc.nextInt();
int temp=num;
while(temp>0)
{
r=temp%10;
if(r==key)
{
flag++;
}
temp/=10;
}
System.out.println(key+" appears "+flag+" times in "+num);
}
}
