Java Lesson: Classes and Instantiation

Specification Sheet

Program: Classes and Instantiation Demonstration

Description: This program introduces beginner programmers to the concept of classes, objects, and instantiation in Java. It includes a basic example of a class with attributes and methods, and how to create and use objects of that class.

Key Concepts:

• Define a class with attributes and methods.
• Create objects (instances) of the class.
• Access and modify object attributes.
• Call methods on an object.

Pseudo Code

1. Define a class called "Car".
    - Add attributes: make (String), model (String), year (int).
    - Add a method: displayCarInfo() to print the car's details.
2. In the main program, create a new object of the "Car" class.
3. Assign values to the attributes of the Car object.
4. Call the displayCarInfo() method to display the car details.
        

Java Program code

// Step 1: Define the class
class Car {
    // Attributes
    String make;
    String model;
    int year;

    // Method to display car details
    void displayCarInfo() {
        System.out.println("Car Details:");
******* you will need to fill in the rest of the java code *******
        

You will drop off 5 files into Google Classroom:
	• Your files will be: (Remember the python program is dropped off first.)
		• PX_lastname_CarClass.java (Java program that is instantiated)
		• PX_lastname_CarClassTester.java (Java program that instantiates the object)
		• PX_lastname_CarClass.png (Screenshot of class notes)
		• PX_lastname_CarClass.png (Screenshot inside Eclipse)
		• PX_lastname_CarClass.mp4 (Video running the program)
