Java Guava | Lists.reverse() method with Examples Last Updated : 04 Feb, 2019 Comments Improve Suggest changes Like Article Like Report Guava's Lists.reverse() method accepts a list as a parameter and returns a reversed view of the list passed as the parameter. If the specified list is random access, then the returned list is also random-access. For example: Lists.reverse(Arrays.asList(1, 2, 3)) returns a list containing 3, 2, 1. Syntax: public static <T> List<T> reverse(List<T> list) Parameter: The method accepts list as a parameter and returns a list which is backed by this list. It means that the changes made in the returned list are reflected back in the list passed as parameter to the method and vice-versa. Return Value: The method Lists.reverse() returns the reversed view of the list passed as parameter. The returned list supports all of the optional list operations supported by the list passed as parameter. Below examples illustrate the implementation of above method: Example 1: Java // Java code to show implementation of // Guava's Lists.reverse() method import com.google.common.collect.Lists; import java.util.Arrays; import java.util.List; class GFG { // Driver's code public static void main(String[] args) { // Creating a List of Integers List<Integer> myList = Arrays.asList(1, 2, 3, 4, 5); // Using Lists.reverse() method to get a // reversed view of the specified list. Any // changes in the returned list are reflected // in the original list and vice-versa List<Integer> reverse = Lists.reverse(myList); // Displaying the reversed view of specified List System.out.println(reverse); } } Output: [5, 4, 3, 2, 1] Example 2: Java // Java code to show implementation of // Guava's Lists.reverse() method import com.google.common.collect.Lists; import java.util.Arrays; import java.util.List; class GFG { // Driver's code public static void main(String[] args) { // Creating a List of Characters List<Character> myList = Arrays.asList('H', 'E', 'L', 'L', 'O'); // Using Lists.reverse() method to get a // reversed view of the specified list. Any // changes in the returned list are reflected // in the original list and vice-versa List<Character> reverse = Lists.reverse(myList); // Displaying the reversed view of specified List System.out.println(reverse); } } Output: [O, L, L, E, H] Reference: https://google.github.io/guava/releases/23.0/api/docs/com/google/common/collect/Lists.html#reverse-java.util.List- Comment More infoAdvertise with us Next Article Java Guava | Lists.reverse() method with Examples S Sahil_Bansall Follow Improve Article Tags : Java java-guava Guava-Functions Guava-Lists Practice Tags : Java Similar Reads Java Tutorial Java is a high-level, object-oriented programming language used to build web apps, mobile applications, and enterprise software systems.
