14. Clear LinkedList

Write a Java program to remove all elements from a linked list.

Sample Solution:-

Java Code:

import java.util.*;
  public class Exercise14 {
  public static void main(String[] args) {
    // create an empty linked list
     LinkedList<String> l_list = new LinkedList<String>();
   // use add() method to add values in the linked list
          l_list.add("Red");
          l_list.add("Green");
          l_list.add("Black");
          l_list.add("Pink");
          l_list.add("orange");
      
     // print the list
   System.out.println("The Original linked list: " + l_list);

  // Removing all the elements from the linked list
    l_list.clear();
 
    System.out.println("The New linked list: " + l_list);
  }
}

Sample Output:

The Original linked list: [Red, Green, Black, Pink, orange]            
The New linked list: []
