要使用ComparatorChain和addComparator，我必须使用什么库？

<dependency>
    <groupId>org.apache.commons</groupId>
    <artifactId>commons-collections4</artifactId>
    <version>4.4</version>
</dependency>

import org.apache.commons.collections4.ComparatorChain;

public class Main {
    public static void main(String[] args) {
        ComparatorChain<String> comparatorChain = new ComparatorChain<>();
        
        // 添加比较器
        comparatorChain.addComparator(String.CASE_INSENSITIVE_ORDER);
        comparatorChain.addComparator((o1, o2) -> o1.length() - o2.length());

        // 使用比较器链进行排序
        List<String> strings = Arrays.asList("apple", "banana", "orange");
        strings.sort(comparatorChain);
        
        System.out.println(strings); // 输出：[apple, orange, banana]
    }
}
