Tell us about your experience using the command pattern in projects

The "Command" pattern allows encapsulating a request or operation as an object, which simplifies managing actions, their order, undo, and redo.

In my projects, I used this pattern to implement Undo/Redo systems and for deferred task execution. For example, each user operation (create, modify, delete) was represented as a separate command object with execute() and undo() methods.

Example:

public interface Command {
    void execute();
    void undo();
}

public class AddTextCommand implements Command {
    private Document doc;
    private String text;

    public AddTextCommand(Document doc, String text) {
        this.doc = doc;
        this.text = text;
    }

    public void execute() {
        doc.addText(text);
    }

    public void undo() {
        doc.removeText(text);
    }
}

This approach improves code extensibility and maintainability by separating operation logic from their invocation.
