Example:

In the example below, the java.util.LinkedList.set() method is used to set the element at the specified position in given list.

import java.util.*;

public class MyClass {
  public static void main(String[] args) {
    //creating a linkedlist
    LinkedList<Integer> MyList = new LinkedList<Integer>();

    //populating linkedlist 
    MyList.add(10);
    MyList.add(20);
    MyList.add(30);
    MyList.add(40);

    //printing linkedlist
    System.out.println("MyList contains: "+ MyList);    

    //modify element at index=2
    MyList.set(2, 100);

    //printing linkedlist
    System.out.println("MyList contains: "+ MyList);  
  }
}

The output of the above code will be:

MyList contains: [10, 20, 30, 40]
MyList contains: [10, 20, 100, 40]
