Find Max and Min Elements of HashSet in Java

Find Max and Min elements of HashSet in Java

HashSet implements the Set interface, backed by a hash table (actually a HashMap instance). 

We can add null elements in HashSet.

• Summary

  To get the maximum element of HashSet, use the Collections.max() method.

 To get the min element of HashSet, use the Collections.max() method.

 
import java.util.*;

public class HashSetExample {

	public static void main(String[] args) {

		// Create HashSet Objects
		HashSet<Integer> set = new HashSet<Integer>();

		set.add(123);
		set.add(45);
		set.add(74);
		set.add(67);
		set.add(54);
		set.add(98);
		set.add(78);

		System.out.println("the Min element in the HasSet is : " + Collections.max(set));

		// Print Maximum value using max method of Collections class
		// 
		System.out.println("the Min element in the HashSet is : " + Collections.min(set));
	}
    
output:
    
    
the Min element in the HashSet is : 123
the Min element in the HashSet is : 45

 

If we have HashSet of DataType Long, still we can use the same methods to find out max and Min elements.
