BJP5 Self-Check 9.8: CarTruck Language/Type: J Java classes inheritance mystery. Author: Marty Stepp (on 2019/09/19) Consider the following two classes: public class Car \{ public void m1() \{ \} System.out.println("car 1); public void m2() \} System.out.println("car 2); public String toString() \{ return "vroom"; \} . public class Truck extends Car \{ public void m1() \{ \} System.out.println("truck 1); And assuming that the following variables have been declared: Car mycar = new Car(); Truck mytruck = new Truck () ; What is the output from the following statements? System.out.print ln (mycar); public class Car \{ public void m1() \} System.out.println("car 1); public void m2() \{ \} System.out.println("car 2); public String toString() return "vroom"; \} public class Truck extends Car \{. public void m1() \{ System.out.println("truck 1); \} And assuming that the following variables have been declared: Car mycar = new Car(); Truck mytruck = new Truck(); What is the output from the following statements? System. out.println(mycar); mycar.m1(); mycar.m2(); System. out. println (mytruck); mytruck.m1()
