您可以在Wardrobe类中添加两个新方法，一个是按颜色过滤的方法，另一个是按尺码过滤的方法。具体实现方法如下：

public ArrayList<Clothes> filterByColor(String color) {
    ArrayList<Clothes> filteredList = new ArrayList<>();
    for (Clothes clothes : clothesList) {
        if (clothes.getColor().equals(color)) {
            filteredList.add(clothes);
        }
    }
    return filteredList;
}

public ArrayList<Clothes> filterBySize(int size) {
    ArrayList<Clothes> filteredList = new ArrayList<>();
    for (Clothes clothes : clothesList) {
        if (clothes.getSize() == size) {
            filteredList.add(clothes);
        }
    }
    return filteredList;
}

然后在WardrobeManagementSystem类中添加两个新的操作：

case 5:
    System.out.println("请输入要查找的颜色：");
    String color = scanner.nextLine();
    ArrayList<Clothes> colorList = wardrobe.filterByColor(color);
    if (colorList.isEmpty()) {
        System.out.println("没有找到符合条件的衣物！");
    } else {
        System.out.println("符合条件的衣物如下：");
        for (Clothes clothes : colorList) {
            System.out.println(clothes.getName() + " (" + clothes.getColor() + ", " + clothes.getSize() + ")");
        }
    }
    break;
case 6:
    System.out.println("请输入要查找的尺码：");
    int size = scanner.nextInt();
    scanner.nextLine();
    ArrayList<Clothes> sizeList = wardrobe.filterBySize(size);
    if (sizeList.isEmpty()) {
        System.out.println("没有找到符合条件的衣物！");
    } else {
        System.out.println("符合条件的衣物如下：");
        for (Clothes clothes : sizeList) {
            System.out.println(clothes.getName() + " (" + clothes.getColor() + ", " + clothes.getSize() + ")");
        }
    }
    break;

这样，用户就可以选择按颜色或尺码查找衣物了。操作5用于按颜色查找，操作6用于按尺码查找。
