There are codes from the Object Oriented Programming course Composite pattern.

1)Can you explain what each line means? 2)Which class is Composite pattern in? 3)What do the methods inside the ProductCatalog class mean?

using System; using System.Collections.Generic; using System.Text; namespace FocusVisualstyle { 7 bavuru public interface ICatalog Component 4 bavuru void DrawHierarchy(); } using System; using System.Windows; using System.Collections.Generic; using System.Text; namespace FocusVisualStyle 5 bavuru public class ProductCatalog : ICatalog Component private string name; private List .components; 4 bavuru public ProductCatalog(string name) { name = name; _components = new List(); 5 bavuru public void Add(ICatalogComponent catalog Component) _components.Add(catalogComponent); O bavuru public void Remove(ICatalog Component catalogComponent) _components. Remove(catalogComponent); 4 bavuru public void DrawHierarchy() MessageBox.Show(_name); foreach (ICatalog Component component in _components) component.DrawHierarchy(); using System; using System.Windows; using System.Collections.Generic; using System.Text; |namespace FocusVisualstyle { 3 bavuru class Product : ICatalog Component { private string name; 2 bavuru public Product(string name) { name = name; } 4 bavuru public void DrawHierarchy() MessageBox.Show(_name)
