The code is not going into catch though I was able to complete the task by keeping the print order code in the try block itself (I know it's not correct). Please help me with the right solution

package com.codegym.task.task09.task0921;

import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.util.ArrayList;
import java.util.List;
import java.util.*;
import java.io.*;

/*
Method in a try-catch

*/

public class Solution {
    public static void main(String[] args) {

        readData();
    }

    public static void readData() {
        //write your code here
       Scanner sc = new Scanner(System.in);
       ArrayList<Integer> arl = new ArrayList<Integer>();

        try {
            while (sc.hasNextInt() ) {
                int i = sc.nextInt();
              //  System.out.println(i);
                arl.add(i);
            }

        }catch (NumberFormatException e) {

            for (int i=0; i <= arl.size(); i++) {
                System.out.println(arl.get(i));
            }
        }
    }
}
