Question

please answer correctly.

Language/Type Java Inheritance polymorphism Assume that the following classes have been defined: public class George extends Elaine ( public void method1() { print("George 1 "); public class Jerry { public void method10) { print("Jerry 1 "); public void method20 { print("Jerry 2 "); public String toString() { return "Jerry": public class Elaine extends Kramer public String toString() { return "Elaine " + super.toString(); public class Kramer extends Jerry public void method1() { super.method1(); print ("Kramer 1"); public void method20 { print("Kramer 2 "); method1(); public String toString() { return "Kramer": Given the classes above, what output is produced by the following code the elements of an array of objects, write the output produced as the lo of the array separately.) Jerry[] seinfeld = { new George(), new Kramer(), new J for (int i = 0; i < seinfeld.length; i++) { seinfeld[i].method1(); println(); seinfeldtime

Answer 1

Element 0
George 1                    // method1 of George called
Kramer 2 George 1         // George extends Elaine which extends Kramer. method2 of Kramer called which calls method1 of George then back again
Elaine Kramer               // toString() of Elaine called which calls toString of Kramer.

Element 1
Jerry 1 Kramer 1            // method1 of Kramer called which calls method1 of Jerry first then prints Kramer 1
Kramer 2 Jerry 1 Kramer 1    // method2 of Kramer called, which prints Kramer 2, then calls its own method1 which calls method1 of Jerry and then prints Kramer 1
Kramer                      // toString of Kramer called

Element 2
Jerry 1                    // method1 of Jerry called
Jerry 2                 // method2 of Jerry called
Jerry                      // toString of Jerry called

Element 3  
Jerry 1 Kramer 1            // Elaine doesn't have method1. method1 of Kramer called which calls method1 of Jerry and then prints Kramer 1
Kramer 2 Jerry 1 Kramer 1   // Elaine doesn't have method2. method2 of Kramer called which prints Kramer 2, then calls method1 of Jerry and then prints Kramer 1
Elaine Kramer               // toString of Elaine called, print Elaine and calls toString of Kramer

Element o George 1 Kramer 2 George 1 Elaine Kramer // methodl of George called // George extends Elaine which extends Kramer. method of Kramer called which calls methodl of George then // toString() of Elaine called which calls toString of Kramer. Element 1 Jerry 1 Kramer 1 Kramer 2 Jerry 1 Kramer 1 Kramer // methodl of Kramer called which calls methodl of Jerry first then prints Kramer 1 // method2 of Kramer called, which prints Kramer 2, then calls its own methodl which calls methodl of Jerry and then prints Kramer 1 // toString of Kramer called Element 2 Jerry 1 Jerry 2 | Jerry // methodl of Jerry called // method2 of Jerry called // toString of Jerry called Element 3 Jerry 1 Kramer 1 Kramer 2 Jerry i Kramer i Elaine Kramer // Elaine doesn't have methodl. methodl of Kramer called which calls methodl of Jerry and then prints Kramer 1 // Elaine doesn't have method2. method2 of Kramer called which prints Kramer 2, then calls methodl of Jerry and then prints Kramer 1 // toString of Elaine called, print Elaine and calls toString of Kramer
