java 字符串list 排序

你可以使用 `Collections.sort()` 方法对字符串列表进行排序，示例如下：

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

public class SortListExample {
    public static void main(String[] args) {
        List<String> stringList = List.of("apple", "banana", "pear", "orange");
        System.out.println("Before sorting: " + stringList);

        Collections.sort(stringList);
        System.out.println("After sorting: " + stringList);
    }
}

输出结果为：

Before sorting: [apple, banana, pear, orange]
After sorting: [apple, banana, orange, pear]

如果你需要按照自定义的顺序进行排序，可以实现 `Comparator` 接口并传递给 `Collections.sort()` 方法，示例如下：

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

public class SortListExample {
    public static void main(String[] args) {
        List<String> stringList = List.of("apple", "banana", "pear", "orange");
        System.out.println("Before sorting: " + stringList);

        Collections.sort(stringList, new LengthComparator());
        System.out.println("After sorting: " + stringList);
    }

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

输出结果为：

Before sorting: [apple, banana, pear, orange]
After sorting: [pear, apple, banana, orange]
