The set() method of AbstractList class in Java

The set() method of the AbstractList class is used to replace the element at the specified position in this list with the specified element. It returns the element that gets replaced.

The syntax is as follows:

public E set(int index, E ele)

Here, the parameter index is the index of the element to replace, whereas ele is the element to be stored at the specified position.

To work with the AbstractList class, import the following package:

import java.util.AbstractList;

The following is an example to implement set() method of the AbstractlList class in Java:

Example

 Live Demo

import java.util.LinkedList;
import java.util.AbstractList;
public class Demo {
   public static void main(String[] args) {
      AbstractList<Integer> myList = new LinkedList<Integer>();
      myList.add(50);
      myList.add(100);
      myList.add(150);
      myList.add(200);
      myList.add(250);
      myList.add(300);
      myList.add(350);
      myList.add(400);
      System.out.println("Elements in the AbstractList class = " + myList);
      System.out.println("Replaced element = " + myList.set(5, 275 ));
      System.out.println("Updated AbstractList = "+myList);
   }
}

Output

Elements in the AbstractList class = [50, 100, 150, 200, 250, 300, 350, 400]
Replaced element = 300
Updated AbstractList = [50, 100, 150, 200, 250, 275, 350, 400]
