Java LinkedList get() Method

The Java LinkedList get(int index) method returns the element at the specified position in this list. Index starts from 0 like first element can be retrieved using get(0) method call and so on.

Following is the declaration for Java.util.LinkedList.get() method

public E get(int index)

index − The index of the element to return.

This method returns the element at the specified position in this list.

IndexOutOfBoundsException − if the index is out of range.

The following example shows the usage of Java LinkedList get(index) method for Integers. We're adding couple of Integers to the LinkedList object using add() method calls per element and using get(index) method, we're getting one of the element by index and printing it.

package com.tutorialspoint;

import java.util.LinkedList;

public class LinkedListDemo {
   public static void main(String[] args) {
      
      // create an empty linked list 
      LinkedList<Integer> linkedList = new LinkedList<>();

      // use add() method to add elements in the linkedList
      linkedList.add(20);
      linkedList.add(30);
      linkedList.add(20);
      linkedList.add(30);
      linkedList.add(15);
      linkedList.add(22);
      linkedList.add(11);

      // let us print the 3rd element
      System.out.println("3rd Element = " + linkedList.get(2));
   }
}

Let us compile and run the above program, this will produce the following result −

3rd Element = 20

The following example shows the usage of Java LinkedList get(index) method for Strings. We're adding couple of Strings to the LinkedList object using add() method calls per element and using get(index) method, we're getting one of the element by index and printing it.

package com.tutorialspoint;

import java.util.LinkedList;

public class LinkedListDemo {
   public static void main(String[] args) {
      
      // create an empty linked list
      LinkedList<String> linkedList = new LinkedList<>();

      // use add() method to add elements in the linkedList
      linkedList.add("Welcome");
      linkedList.add("To");
      linkedList.add("Tutorialspoint");
	  
      // let us print the 3rd element
      System.out.println("3rd Element = " + linkedList.get(2));     
   }
}

Let us compile and run the above program, this will produce the following result −

3rd Element = Tutorialspoint

The following example shows the usage of Java LinkedList get(index) method for Student objects. We're adding couple of Student objects to the LinkedList object using add() method calls per element and using get(index) method, we're getting one of the element by index and printing it.

package com.tutorialspoint;

import java.util.LinkedList;

public class LinkedListDemo {
   public static void main(String[] args) {

      // create an empty linkedList
      LinkedList<Student> linkedList = new LinkedList<>();

      // use add() method to add elements in the linkedList
      linkedList.add(new Student(1, "Julie"));
      linkedList.add(new Student(2, "Robert"));
      linkedList.add(new Student(3, "Adam"));

      // let us print the 3rd element
      System.out.println("3rd Element = " + linkedList.get(2));      
   }
}

class Student {
   int rollNo;
   String name;

   Student(int rollNo, String name){
      this.rollNo = rollNo;
      this.name = name;
   }

   @Override
   public String toString() {
      return "[ " + this.rollNo + ", " + this.name + " ]";
   }
}

Let us compile and run the above program, this will produce the following result −

3rd Element = [ 3, Adam ]
