What is the output of the following code with the provided classes?

public class Polymorphism { public static void main(String[] args) { Mars[] arr = {new Mercury(), new Jupiter(), new Mars(), new Saturn()}; for(Mars element : arr) { element.method2(); element.method1(); System.out.println(element); System.out.println(); } } }

public class Jupiter extends Saturn { public void method1() { System.out.println("Saturn1"); } }

public class Saturn extends Mars { public String toString() { return "Saturn"; } }

public class Mars { public void method1() { System.out.println("Mars1"); } public void method2() { System.out.println("4th Planet"); } public String toString() { return "Mars"; } }

public class Mercury extends Saturn { public void method2() { System.out.println("6th planet"); } public String toString() { return "Saturn"; } }
