How do I use classes in Java?

In Java, a class is a blueprint for creating objects. You define a class using the 'class' keyword.

Can you give me an example of a simple class?

Sure! Here's a simple class definition:

public class Dog {
    String name;
    int age;

    public void bark() {
        System.out.println("Woof!");
    }
}

How do I create an object from this class?

You can create an object by using the 'new' keyword like this:

Dog myDog = new Dog();
myDog.name = "Buddy";
myDog.age = 3;
myDog.bark();

What are constructors in Java classes?

Constructors are special methods that are called when an object is instantiated. They can initialize object properties.
