删除List <T>中的备用元素

import java.util.ArrayList;
import java.util.List;

public class Main {
    public static void main(String[] args) {
        List<String> list = new ArrayList<>();
        list.add("A");
        list.add("B");
        list.add("C");

        System.out.println("Original List: " + list);

        // 删除指定元素
        list.remove("B");

        System.out.println("List after removing 'B': " + list);
    }
}

Original List: [A, B, C]
List after removing 'B': [A, C]
