How do I get the user input to go in the if statement? I'm new to java so I don't know how to fix

1.I want to print out the animals names and what the user inputs at the end of the program that can fit in a spreadsheet. e.g. 500, panthers.

import java.util.Scanner;//import scanner so user can input

class arrays {

   public static void main(String[] param){

       String[] animals = arrays(); // creating string array to store information
       forloop(animals);// passing the array to the method forloop
       System.exit(0);
   } //end main method

   public static String[] arrays() {

       String[] animals = new String[5]; //array to store 5 animals
       animals[0] = "Dragon"; //animals stored
       animals[1] = "Bee";
       animals[2] = "Poon";
       animals[3] = " Panther";
       animals[4] = "White Ants";

       return animals;
   }

   public static void forloop(String[] animals) {

       for(int i =0; i<5; i++) //for loop to print the below 
       //print 5 times using the different animal names.
       {
           String ans;
           System.out.println(animals[i] + ":");
           System.out.println("How many are left?"); // prints the question
           Scanner scanner = new Scanner(System.in); // allows the user to input
           ans = scanner.nextLine();

2.if statement used to print out the smallest number types by the user. How do I do this? I want to use the

   if(ans<=20) {
    System.out.println("The most dangerous animal is the " + animals[i] + "."); // prints out the most dangerous animal
        System.out.println("There are only 10 left.");
    }
    }
}

}
