In the following main(), identify the valid or invalid statements. If invalid, tell why. ```java public class TestMain { public static void main(String[] args) { Car myCar1, myCar2; ElectricCar myElec1, myElec2; myCar1 = new Car(); __________________________ myCar2 = new Car("Ford", 1200, "Green"); __________________________ myElec1 = new ElectricCar(); __________________________ myElec2 = new ElectricCar(15); __________________________ } } ``` **Explanation of Code:** - **Car myCar1, myCar2;** - This line declares two variables, `myCar1` and `myCar2`, as instances of the class `Car`. - **ElectricCar myElec1, myElec2;** - This line declares two variables, `myElec1` and `myElec2`, as instances of the class `ElectricCar`. - **myCar1 = new Car();** - This initializes `myCar1` using a default constructor. The validity depends on whether the `Car` class has a default constructor defined. - **myCar2 = new Car("Ford", 1200, "Green");** - This initializes `myCar2` with specified parameters. The validity depends on whether the `Car` class has a constructor that takes a `String`, an `int`, and another `String` as arguments. - **myElec1 = new ElectricCar();** - This initializes `myElec1` using a default constructor. Similar to `myCar1`, its validity depends on the existence of a default constructor in the `ElectricCar` class. - **myElec2 = new ElectricCar(15);** - This initializes `myElec2` with a specified integer parameter. The validity depends on whether the `ElectricCar` class has a constructor that takes an `int` as an argument. Certainly! Here is the transcription of the class definitions in the image: --- ### Class Definitions #### 1. Car Class ```java class Car { public String make; protected int weight; private String color; private Car(String make, int weight, String color) { this.make = make; this.weight = weight; this.color = color; } public Car() { this("Unknown", -1, "white"); } } ``` #### 2. ElectricCar Class ```java public class ElectricCar extends Car { private int rechargeHour; public ElectricCar() { this(0); } private ElectricCar(int charge) { super(); rechargeHour = charge; } } ``` --- **Explanation:** - **Car Class:** - The `Car` class defines three attributes: `make`, `weight`, and `color`. - The constructor initializes these attributes and provides a default constructor that gives default values. - **ElectricCar Class:** - The `ElectricCar` class extends the `Car` class, inheriting its properties and methods. - It includes an additional attribute `rechargeHour`. - Two constructors are defined: a default constructor and a parameterized constructor to initialize `rechargeHour`. **Note:** There are no graphs or diagrams in the image.
