java - 如何检查元素是否在Java的ArrayList中找到？

我有一个arrayList，我想搜索特定项目并对其执行操作，如下所示：

System.out.print("What is the ID of the shop that you want to delete?");
              int removedShopID= Integer.parseInt(in.next());

       for(int i=0; i<shops.size(); i++){
               if(shops.get(i).getID()==removedShopID)
                { shops.remove(i);
   System.out.println("The shop has been successfully deleted.");}

                         }


}

它工作正常，但是如果没有ID匹配，我需要添加一条语句，它将显示“未找到”或类似内容。有什么帮助吗？

最佳答案

展示khelwood的含义：

public static void main(String[] args) {

    List<Shop> shops = new LinkedList<Shop>();

    System.out.print("What is the ID of the shop that you want to delete?");
    Scanner scanner = new Scanner(System.in);
    int removedShopID = scanner.nextInt();

    boolean isFound = false;
    for (int i = 0; i < shops.size(); i++) {
        if (shops.get(i).getID() == removedShopID) {
            shops.remove(i);
            isFound = true;
            System.out.println("The shop has been successfully deleted.");
        }
    }
    if (!isFound) {
        System.out.println("Not found!");
    }
}
