How do you use objects with a simple code example?

In Java, objects are instances of classes that encapsulate data and behaviors. Here's a simple example demonstrating how to create a class, instantiate an object, and use its methods:


        // Define a class called Dog
        class Dog {
            // Attributes (properties) of the class
            String name;
            int age;

            // Constructor to initialize a Dog object
            Dog(String name, int age) {
                this.name = name;
                this.age = age;
            }

            // Method to display dog's info
            void displayInfo() {
                System.out.println("Dog's Name: " + name);
                System.out.println("Dog's Age: " + age);
            }
        }

        // Main class to run the program
        public class Main {
            public static void main(String[] args) {
                // Create a Dog object
                Dog myDog = new Dog("Buddy", 3);
                
                // Call the displayInfo method
                myDog.displayInfo();
            }
        }
