Java – Remove all elements from LinkedList example

In this example we will see how to remove all the elements from LinkedList. We will be using clear() method of LinkedList class to do this. Method definition and description are as follows:

public void clear(): Removes all of the elements from this list. The list will be empty after this call returns.

Example

In this example we have a LinkedList of String type that has 5 elements. We are calling clear() method and displaying the LinkedList elements before and after calling the clear() method.

import java.util.LinkedList;
public class RemoveAllExample {
 
 public static void main(String[] args) {
 
    // Create a LinkedList
    LinkedList<String> linkedlist = new LinkedList<String>();
 
    // Add elements to LinkedList
    linkedlist.add("Item1");
    linkedlist.add("Item2");
    linkedlist.add("Item3");
    linkedlist.add("Item4");
    linkedlist.add("Item5");
 
    // Displaying Elements before remove
    System.out.println("Before clear():");
    for(String str: linkedlist){
       System.out.println(str);
    }
 
    // Removing all the elements from LinkedList
    linkedlist.clear();
 
    // LinkedList elements after remove
    System.out.println("After clear():");
    for(String str2: linkedlist){
       System.out.println(str2);
    }
 }
}

Output:

Before clear():
Item1
Item2
Item3
Item4
Item5
After clear():
