Intermediate Java(9)- Collections Method sort

import java.util.*;

public class apples{

public static void main(String[] args){

String[] things={"apple","orange","lemon","mango","cheese"};

List<String> list1 = Arrays.asList(things);

Collections.sort(list1); → 為陣列排序

System.out.printf("%s\n",list1);

Collections.sort(list1, Collections.reverseOrder()); → 為陣列反轉排序

System.out.printf("%s\n",list1);

}

}

這是運行時的結果:

[apple, cheese, lemon, mango, orange]

[orange, mango, lemon, cheese, apple]
