import java.util.*;

public class Main {
   public static void main(String[] args) {
      LinkedList<String> lList = new LinkedList<String>();
      lList.add("1");
      lList.add("8");
      lList.add("6");
      lList.add("4");
      lList.add("5");
      System.out.println(lList);
      lList.subList(2, 4).clear();
      System.out.println(lList);
   }
}

Result

The above code sample will produce the following result.

[one, two, three, four, five]
[one, two, three, Replaced, five]

The following is an another sample example to delete many elements of linkedList using Clear() method.

import java.util.LinkedList;
 
public class Demo {
   public static void main(String[] args) {
      LinkedList lList = new LinkedList();
      lList.add("1");
      lList.add("2");
      lList.add("3");
      lList.add("4");
      lList.add("5");
      System.out.println("LinkedList is : " +lList);
      lList.subList(2, 4).clear();
      System.out.println("LinkedList is : " +lList);
   }
}

The above code sample will produce the following result.

LinkedList is : [1, 2, 3, 4, 5]
LinkedList is : [1, 2, 5]
