Find maximum element of ArrayList with Java Collections

Java 8Object Oriented ProgrammingProgramming

In order to compute maximum element of ArrayList with Java Collections, we use the Collections.max() method. The java.util.Collections.max() returns the maximum element of the given collection. All elements must be mutually comparable and implement the comparable interface. They shouldn’t throw a ClassCastException.

Declaration −The Collections.max() method is declared as follows −

public static <T extends Object & Comparable> T max(Collection c)

where c is the collection object whose maximum is to be found.

Let us see a program to find the maximum element of ArrayList with Java collections −


 Live Demo

import java.util.*;
public class Example {
   public static void main (String[] args) {
      List<Integer> list = new ArrayList<Integer>();
      try {
         System.out.println("Maximum element : " + Collections.max(list));
      catch (ClassCastException | NoSuchElementException e) {
         System.out.println("Exception caught : " + e);


Maximum element : 73
