java中的排序

Java中对list中字符串进行排序

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

public class SortTest {
    public static void main(String[] args) {
        List<String> list = new ArrayList<>();
        list.add("collection_2019_3_4");
        list.add("collection_2019_3_7");
        list.add("collection_2019_3_10");
        list.add("collection_2019_3_13");
        Collections.sort(list, new Comparator<String>() {
            @Override
            public int compare(String s1, String s2) {
                return s1.compareTo(s2);
            }
        });
       for(int i = 0; i < list.size(); i ++){
           System.out.println(list.get(i));
       }
    }
}
