how to use the instanceof method correctly

The task is given: Create a static printMagazines(Printable[] printable) method in the Magazine class that outputs only the names of the magazines to the console. Create a static method printBooks (Printable[] printable) in the Book class, which outputs only the names of books to the console. We use the instanceof operator. I wrote the method, but its execution leads to an error. Please help:) Code:

public class Main {
    public static void main(String[] args) {
 Printable[] test=new Printable[3];
 test[0]=new Book();
 test[1]=new Magazine("keke");
 test[2]=new Book();
        int k=0;
 for (Printable i:test){
     test[k].print();
k++;
 }
     **if   (test[k] instanceof Magazine){
         int l=0;
       ((Magazine) test[k]).printMagazines(test);
         k++;
     }**
    }}

public interface Printable {
    Printable print();
}

public class Book implements Printable {
    String name;
    @Override
    public Printable print() {
        System.out.println("1");
        return null;
    }
   public void printBooks(Printable[] printable){
       Printable b=print();
       System.out.println(b);
   }
}

public class Magazine implements Printable {
String name;
Magazine(String name){
    this.name=name;
}
    @Override
    public Printable print() {
        System.out.println("2");
        return null;
    }
   public void    printMagazines(Printable[] printable){
       System.out.println(name);
    }
}

Mistake: Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: Index 3 out of bounds for length 3 at Main.main(Main.java:19)

Thank you in advance!
