The get the first element we can use the LinkedList.getFirst()
method and to get the last element we can use the LinkedList.getLast()
method.
package org.kodejava.util;
import java.util.LinkedList;
public class LinkedListGetFirstLast {
public static void main(String[] args) {
LinkedList<String> names = new LinkedList<>();
names.add("Alice");
names.add("Bob");
names.add("Carol");
names.add("Mallory");
// Get the first and the last element of the linked list
String first = names.getFirst();
String last = names.getLast();
System.out.println("First member = " + first);
System.out.println("Last member = " + last);
}
}
The program will print the following result:
First member = Alice
Last member = Mallory
