Question

WAP to display all the numbers between 100 and 150 which contain zeros at any position.
For example: 100,101,102….110 etc. In java

Answer 1

Explanation:

import java.util.Scanner;

public class KboatSeries

{

public void computeSum() {

Scanner in = new Scanner(System.in);

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

int a = in.nextInt();

System.out.print("Enter n: ");

int n = in.nextInt();

double sum = 0;

int lastPrime = 1;

for (int i = 1; i <= n; i++) {

for (int j = lastPrime + 1; j <= Integer.MAX_VALUE; j++) {

boolean isPrime = true;

for (int k = 2; k <= j / 2; k++) {

if (j % k == 0) {

isPrime = false;

break;

}

}

if (isPrime) {

sum += j / Math.pow(a, i);

lastPrime = j;

break;

}

}

}

System.out.println("Sum=" + sum);

}

}
