如何为组件编写抽象类(使用可扩展的状态和属性)？

abstract class Component {
    protected String name;
    protected int size;

    public Component(String name, int size) {
        this.name = name;
        this.size = size;
    }

    public abstract void render();

    public abstract void onClick();

    public void setSize(int size) {
        this.size = size;
    }

    public int getSize() {
        return size;
    }
}

class Button extends Component {
    private String text;

    public Button(String name, int size, String text) {
        super(name, size);
        this.text = text;
    }

    @Override
    public void render() {
        System.out.println("Rendering button: " + name);
    }

    @Override
    public void onClick() {
        System.out.println("Button clicked: " + text);
    }
}

class TextBox extends Component {
    private String value;

    public TextBox(String name, int size, String value) {
        super(name, size);
        this.value = value;
    }

    @Override
    public void render() {
        System.out.println("Rendering text box: " + name);
    }

    @Override
    public void onClick() {
        System.out.println("Text box clicked: " + value);
    }
}

public class Main {
    public static void main(String[] args) {
        Button button = new Button("Submit", 100, "Submit");
        button.render();
        button.onClick();

        TextBox textBox = new TextBox("Username", 200, "");
        textBox.render();
        textBox.onClick();
    }
}
