Remove a range of elements from a LinkedList in Java
A range of elements can be removed from a LinkedList by using the method java.util.LinkedList.clear() along with the method java.util.LinkedList.subList(). A program that demonstrates this is given as follows −
Example
import java.util.LinkedList;
public class Demo {
public static void main(String[] args) {
LinkedList<String> l = new LinkedList<String>();
l.add("Clark");
l.add("Bruce");
l.add("Diana");
l.add("Wally");
l.add("Oliver");
System.out.println("The LinkedList is: " + l);
l.subList(1,3).clear();
System.out.println("The LinkedList is: " + l);
}
}Output
The LinkedList is: [Clark, Bruce, Diana, Wally, Oliver] The LinkedList is: [Clark, Wally, Oliver]
Now let us understand the above program.
The LinkedList l is created. Then LinkedList.add() is used to add the elements to the LinkedList. Then the LinkedList is displayed. A code snippet which demonstrates this is as follows −
LinkedList<String> l = new LinkedList<String>();
l.add("Clark");
l.add("Bruce");
l.add("Diana");
l.add("Wally");
l.add("Oliver");
System.out.println("The LinkedList is: " + l);A range of elements from index 1(inclusive) to index 3(exclusive) are removed from the LinkedList using the LinkedList.clear() and the LinkedList.subList() methods. Then the modified LinkedList is displayed. A code snippet which demonstrates this is as follows −
System.out.println("The LinkedList is: " + l);
l.subList(1,3).clear();
System.out.println("The LinkedList is: " + l);
