        set.add("Geeks"); 
  
        // Displaying the LinkedHashSet 
        System.out.println("LinkedHashSet: " + set); 
  
        // Removing elements using remove() method 
        set.remove("Geeks"); 
        set.remove("4"); 
        set.remove("Welcome"); 
  
        // Displaying the LinkedHashSet after removal
