Previously we have discussed the Program for 
In Java Which run first Static Block, Block, Constructor or Method() ?

Today we learn how to find Minimum and Maximum value from Array List using predefined method available in java.util.Collections; package i.e Collections.min(Object obj); to find minimum element and Collections.max(Object obj); to find maximum element.

import java.util.ArrayList;

import java.util.Collections;

public class MinAndMax {

 public static void main(String[] args)  {

  ArrayList al=new ArrayList();

  al.add(2);

  al.add(0);

  al.add(5);

  al.add(8);

  al.add(6);

  al.add(3);

  System.out.println("given array is :" + al);

  int n=Collections.min(al);

  System.out.println("Minimum value in array is:"+ n);

  

  int m=Collections.max(al);

  System.out.println("Maximum value in array is:"+ m);

 }

}

Program Output :-

given array is :[2, 0, 5, 8, 6, 3]

Minimum value in array is:0

Maximum value in array is:8
