How to add elements to AbstractSequentialList class at a specific position in Java?
The AbstractSequentialList class has the add() method to add an element to the specific position.The syntax is as followsadd(int index, E ele)Here, index is where the element is to be inserted. The ele is the element to be inserted.To work with the AbstractSequentialList class in Java, you need to import the following packageimport java.util.AbstractSequentialList;The following is an example to implement AbstractSequentialList add() method in JavaExampleimport java.util.LinkedList; import java.util.AbstractSequentialList; public class Demo { public static void main(String[] args) { AbstractSequentialList absSequential = new LinkedList(); absSequential.add(0, 50); absSequential.add(1, 30); ...
