Java字典序排序

Java中对List进行字典序排序

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

private List list = new ArrayList<>();

Collections.sort(list, new Comparator() {
            @Override
            public int compare(Type o1, Type o2) {
                return o1.compareTo(o2);
            }
        });
//倒序排列
Collections.reverse(list);
