Remove all elements from hashset in java

We can use clear() method to remove all elements from hashset in java.

Syntax:

hashSet.clear();

Example:

package com.w3spoint;
 
import java.util.HashSet;
 
public class Test {	 
    public static void main(String[] args) {
    	//Create HashSet object
    	HashSet<String> hashSet = new HashSet<String>();
        //Add elements to HashSet
    	hashSet.add("Jai");
    	hashSet.add("Mahesh");
    	hashSet.add("Vivek");
    	hashSet.add("Naren");
    	hashSet.add("Vishal");
    	hashSet.add("Hemant");
    	System.out.println("HashSet: " + hashSet);
    	hashSet.clear();
        System.out.println("HashSet after modification: " + hashSet);
    }
}

Output

HashSet: [Naren, Jai, Vivek, Hemant, Mahesh, Vishal]
HashSet after modification: []
