java list string排序

可以使用Collections.sort(List<T>)方法对List<String>进行排序。示例如下：

import java.util.Collections;
import java.util.List;

public class Main {
    public static void main(String[] args) {
        List<String> list = List.of("apple", "banana", "orange", "pear");
        Collections.sort(list);
        System.out.println(list);
    }
}

输出结果为：

[apple, banana, orange, pear]

如果要实现自定义排序，可以使用Comparator接口，示例如下：

import java.util.Collections;
import java.util.Comparator;
import java.util.List;

public class Main {
    public static void main(String[] args) {
        List<String> list = List.of("apple", "banana", "orange", "pear");
        Collections.sort(list, new StringLengthComparator());
        System.out.println(list);
    }
}

class StringLengthComparator implements Comparator<String> {
    @Override
    public int compare(String s1, String s2) {
        return Integer.compare(s1.length(), s2.length());
    }
}

输出结果为：

[pear, apple, banana, orange]
