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.

The manoeuvre The vertical and slow-move-vertical methods are the ones that need to be practised initially. To move the circle to a place that is 70 pixels to the left of where it is now located in your document, use the moveHorizontal command.

First Column: Merge column 1, column 2 and column 3. Set the background color as "blue" and align the contents to the right. Insert a Search Form. Insert a suitable input type to select items like SUBJECTS, COURSES, CV HELP and JOB MARKET. Set any name for the form field. Insert a suitable input type to enter the search text. Set any name for the text field and the maximum length is 40. Insert a submit button with a value SEARCH COURSES. • Set a form validation using JAVASCRIPT. If the form field (search) is empty. display an alert message and return false to prevent the form from being submitted.

The moveVertical and slowMoveVertical strategies should be practiced first. Use the moveHorizontal command to 70 pixels to the left of the current position of the circle in your document.

Create the page layout as shown in the screenshot above. In particular, we will call the top, bottom, left, and right portions of the page "header", "footer", "content", and "menu", respectively. Note that the content part of the page is further divided into three blocks: the top block has a heading and a paragraph, and is followed by two blocks - one on the left with two images, and one on the right with three "announcements". The header should use large, white, center-aligned text on a red background with a thick black border. There should be some space between the text and the border. The footer should use green, centered-aligned text on a gray background.  The menu has an unordered list on a black background. The background of the list is red. Each item in the list is hyperlinked except for "Home". The unlinked text should be black, and the linked text should be white. When a user mouse over a link, the color of the text should change to black. There should be some space between…
