A simple yet essential concept that comes up often in coding tests! Ekbet Login

public static void main(String[] args) {
    Scanner scan = new Scanner(System.in);
    System.out.println((scan.hasNextInt()) ? ("Good job") : ("Wrong answer"));
    scan.close(); 
}

This is one of those basic yet essential concepts that often comes up in coding challenges, especially on platforms like HackerRank. Mahadev book

import java.io.; import java.util.;

public class Solution {

public static void main(String[] args) {

    int n = 100;

    String num = Integer.toString(n);

    if(num instanceof String){
        System.out.println("Good job");
    }
    else{
        System.out.println("Wrong answer");
    }
}

}

Here is the simple and straight forward approach

import java.io.; import java.util.;

public class Solution {

public static void main(String[] args) {

    int n = 100;

    String num = "";

    num = Integer.toString(n);

    if(num instanceof String){
        System.out.println("Good job");
    }
    else{
        System.out.println("Wrong answer");
    }
}

}
