Using Java to develop the divided storage and mixed warehousing functions of the warehouse management system

public class Warehouse { private List storageAreas; // 构造方法初始化多个储存区域 public Warehouse() { storageAreas = new ArrayList<>(); storageAreas.add(new StorageArea("A", 100)); storageAreas.add(new StorageArea("B", 200)); storageAreas.add(new StorageArea("C", 150)); } // 将商品存储到指定的区域 public void storeProduct(Product product, String areaName) { for (StorageArea area : storageAreas) { if (area.getName().equals(areaName)) { area.storeProduct(product); break; } } } // 从指定区域取出指定数量的商品 public List retrieveProduct(String areaName, int quantity) { List result = new ArrayList<>(); for (StorageArea area : storageAreas) { if (area.getName().equals(areaName)) { result = area.retrieveProduct(quantity); break; } } return result; } } public class StorageArea { private String name; private int capacity; private List products; public StorageArea(String name, int capacity) { this.name = name; this.capacity = capacity; products = new ArrayList<>(); } public void storeProduct(Product product) { if (products.size() < capacity) { products.add(product); System.out.println("商品存储成功！"); } else { System.out.println("该区域已满，无法继续存储商品！"); } } public List retrieveProduct(int quantity) { List result = new ArrayList<>(); if (products.size() >= quantity) { for (int i = 0; i < quantity; i++) { result.add(products.remove(0)); } System.out.println("商品取出成功！"); } else { System.out.println("该区域商品数量不足！"); } return result; } // getters and setters... } public class Product { private String name; private double price; // getters and setters... }

public class Warehouse { private Map> productCategories; public Warehouse() { productCategories = new HashMap<>(); } public void storeProduct(Product product, String category) { if (!productCategories.containsKey(category)) { productCategories.put(category, new ArrayList<>()); } productCategories.get(category).add(product); System.out.println("商品存储成功！"); } public List retrieveProduct(String category, int quantity) { if (!productCategories.containsKey(category)) { System.out.println("该类别商品不存在！"); return new ArrayList<>(); } List categoryProducts = productCategories.get(category); List result = new ArrayList<>(); if (categoryProducts.size() >= quantity) { for (int i = 0; i < quantity; i++) { result.add(categoryProducts.remove(0)); } System.out.println("商品取出成功！"); } else { System.out.println("该类别商品数量不足！"); } return result; } } public class Product { private String name; private double price; // getters and setters... }
