Here is an example of ArrayList which finds the maximum and minimum value element from the ArrayList. Java provides direct methods to get maximum and minimum value from any collection class i.e max() and min() respectively.

import java.util.*;

class FindMaxMinUsingCollection 
{
    public static void main(String[] args){

        ArrayList<Integer> list = new ArrayList<Integer>();
        list.add(50);
        list.add(15);
        list.add(450);
        list.add(550);
        list.add(200);
        Object minValue = Collections.min(list);
        Object maxValue = Collections.max(list);
        System.out.println("Minimum value is = " + minValue);
        System.out.println("Maximum value is = " + maxValue);

    }
 }
