Remove element from LinkedHashSet example

In this example we shall show you how to remove an element from a LinkedHashSet, using the remove(Object o) method of LinkedHashSet. To remove an element from a LinkedHashSet one should perform the following steps:

  • Create a new LinkedHashSet.
  • Populate the set with elements, using the add(E e) API method of LinkedHashSet.
  • Remove an element from the set, using remove(Object o) API method of LinkedHashSet. The method removes the specified element from the set, if the set contains that element and returns true,

as described in the code snippet below.

package com.javacodegeeks.snippets.core;

import java.util.LinkedHashSet;
public class RemoveElementLinkedHashSet {
  public static void main(String[] args) {
    // Create a LinkedHashSet and populate it with elements
    LinkedHashSet linkedHashSet = new LinkedHashSet();

    System.out.println("LinkedHashSet contents : " + linkedHashSet);

    // boolean remove(Object o) method removes the specific object from the LinkedHashSet if present and returns true, false otherwise
    boolean removed = linkedHashSet.remove("element_2");
    System.out.println("LinkedHashSet contents after removal of element_2 : " + linkedHashSet);



LinkedHashSet contents : [element_1, element_2, element_3]
LinkedHashSet contents after removal of element_2 : [element_1, element_3]

This was an example of how to remove an element from a LinkedHashSet in Java.
