Why am i getting this error?

#1

Exception in thread “main” java.util.NoSuchElementException

Please check my Code.

import java.util.*;
public class Main {

public static void printMajority(int[] arr) {
    int n = arr.length;

    HashMap<Integer,Integer> map = new HashMap<>();

    for(int i=0;i<n;i++) {
        if(map.containsKey(arr[i])) {
            map.put(arr[i],map.get(arr[i])+1);
        } else {
            map.put(arr[i],1);
        }
    }

    for(Map.Entry<Integer,Integer> data : map.entrySet()) {
        if(data.getValue() > n/3) {
            System.out.print(data.getValue() + " ");
        }
    }

}
public static void main (String args[]) {
    Scanner in = new Scanner(System.in);
    int count = in.nextInt();
    int arr[] = new int[count];

    for (int i = 0; i < count; i++) {
        arr[i] = in.nextInt();
    }
    printMajority(arr);

}

}

Hi Shivam
You were running the program without providing any input. That is why there was a noelementException.

First provide input before running the program
