Question

Create a java class that user put two inputs

and first input generate n length array of randomly generated numbers. and the second input changes that number of multiples in the array into zero. for example,

if the user puts 3 and 5 then it generates 34 60 10 and since the second input is 5 then the multiple of 5 eliminates so it generates 34 0 0

here is the main method that I'm going to use

class Main {
public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
       Random ran = new Random();
       int fiv = sc.nextInt();
       int n = sc.nextInt();
       ran.setSeed(n);
      
       int[] arr = new int[n];
       for (int i = 0; i < n; i++)
           arr[i] = ran.nextInt(100);
      
       for (int i = 0; i < n; i++)
       System.out.print(arr[i] + " ");
       System.out.println();
      
       Eliminator.eliminate(arr, fiv);
       for (int i = 0; i < n; i++)
           System.out.print(arr[i] + " ");
      
sc.close();
}
}

Answer 1

//Eliminator.java
public class Eliminator {
  public static void eliminate(int[] arr, int fiv) {
    for(int i = 0;i<arr.length;i++){
      if(arr[i]%fiv == 0){
        arr[i] = 0;
      }
    }
  }
}

=====================================

//Main.java
import java.util.Random;
import java.util.Scanner;
public class Main {
  public static void main(String[] args) {
    Scanner sc = new Scanner(System.in);
    Random ran = new Random();
    int n = sc.nextInt();
    int fiv = sc.nextInt();
    ran.setSeed(n);

    int[] arr = new int[n];
    for (int i = 0; i < n; i++)
      arr[i] = ran.nextInt(100);

    for (int i = 0; i < n; i++)
      System.out.print(arr[i] + " ");
    System.out.println();

    Eliminator.eliminate(arr, fiv);
    for (int i = 0; i < n; i++)
      System.out.print(arr[i] + " ");

    sc.close();
  }
