How to Find Min Element of Java HashSet

In this example we will show how to find a minimum element of HashSet with min method of Collections class in Java.

Source Code

package com.beginner.examples;

import java.util.Collections;
import java.util.HashSet;

public class FindMinimumOfHashSet {

	public static void main(String[] args) {
		
		//create HashSet.
		HashSet hashSet = new HashSet();
		
		hashSet.add(new Integer("2547"));
		hashSet.add(new Integer("958"));
		hashSet.add(new Integer("32587"));
		
		/*
		 To find minimum element of Java HashSet use static Object min(Collection c) method of Collections.
		*/
		Integer result = Collections.min(hashSet);
		System.out.println("The minimum element is " + result);
	}

}

Output:
