What languages support the Composite Pattern?

Can you tell me which programming languages support the Composite Pattern?

The Composite Pattern is supported in many programming languages, including Java, C#, C++, and Python. Would you like to know how it's implemented in a specific language?

Yes, how is it implemented in Java?

In Java, the Composite Pattern can be implemented using interfaces or abstract classes to define a component, and then creating leaf and composite classes that implement this component. Would you like to see a code example?

That would be great! Please show me a code example.

Sure! Here's a simple example:

interface Component {
    void operation();
}

class Leaf implements Component {
    public void operation() {
        System.out.println("Leaf operation");
    }
}

class Composite implements Component {
    private List<Component> children = new ArrayList<>();

    public void add(Component component) {
        children.add(component);
    }

    public void operation() {
        for (Component child : children) {
            child.operation();
        }
    }
}

This code defines a Component interface, a Leaf class, and a Composite class that can hold multiple children.
