.reverse()
The Collections.reverse()
method reverses the current ordering of a List
.
Syntax
import java.util.*;
Collections.reverse(myList);
This reverses the ordering of the elements in myList
.
Example
The following example creates an ArrayList
and then uses Collections.reverse()
to reorder the elements:
import java.util.*;public class Main {public static void main(String[] args) {ArrayList<String> food = new ArrayList<String>();food.add("Cabbage");food.add("Pizza");food.add("Sausage");food.add("Potatoes");food.add("Salad");System.out.println(food);Collections.reverse(food);System.out.println(food);}}
This will output the following:
[Cabbage, Pizza, Sausage, Potatoes, Salad][Salad, Potatoes, Sausage, Pizza, Cabbage]
