The contains() method of AbstractSequentialList in Java

The contains() method of AbstractSequentialList in Java is used to check whether an element is in the Collection.

The syntax is as follows

public boolean contains(Object ob)

Here, ob is the element to be checked. To work with the AbstractSequentialList class in Java, you need to import the following package

import java.util.AbstractSequentialList;

The following is an example to implement AbstractSequentialList contains() method in Java

Example

 Live Demo

import java.util.LinkedList;
import java.util.AbstractSequentialList;
public class Demo {
   public static void main(String[] args) {
      AbstractSequentialList<Integer> absSequential = new LinkedList<>();
      absSequential.add(250);
      absSequential.add(320);
      absSequential.add(400);
      absSequential.add(550);
      absSequential.add(600);
      absSequential.add(700);
      absSequential.add(900);
      System.out.println("Elements in the AbstractSequentialList = "+absSequential);
      System.out.println("Does the element exist? = " + absSequential.contains(400));
   }
}

Output

Elements in the AbstractSequentialList = [250, 320, 400, 550, 600, 700, 900]
Does the element exist? = true
