Get first element in linked list in java

by

Following methods are used to get first element in linked list in java:

  • element(): Retrieves, but does not remove, the head (first element) of this list.
  • getFirst(): Returns the first element in this list.
  • peek(): Retrieves, but does not remove, the head (first element) of this list.
  • peekFirst(): Retrieves, but does not remove, the first element of this list, or returns null if this list is empty.

Example:

package com.w3schools;
 
import java.util.LinkedList;
 
public class Test {
  public static void main(String args[]){
	LinkedList<String> linkedList = new LinkedList<String>();
	linkedList.add("Jai");
	linkedList.add("Mahesh");
	linkedList.add("Naren");
	linkedList.add("Vivek");
	linkedList.add("Vishal");
	linkedList.add("Hemant");
	System.out.println("Actual LinkedList:"+linkedList);
	System.out.println("First Element: "+linkedList.element());
        System.out.println("First Element: "+linkedList.getFirst());
        System.out.println("First Element: "+linkedList.peek());
        System.out.println("First Element: "+linkedList.peekFirst());
  }
}

Output
