Syntax error The hashCode() method of AbstractList class in Java

The hashCode() method of AbstractList class in Java

The hashCode() method of AbstractList class returns the hash code value for this list.

The syntax is as follows:

public int hashCode()

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

import java.util.AbstractList;

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

Example

 Live Demo

import java.util.ArrayList;
import java.util.AbstractList;
public class Demo {
   public static void main(String[] args) {
      AbstractList<Integer> myList = new ArrayList<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("HashCode = " + myList.hashCode());
   }
}

Output

Elements in the AbstractList class = [50, 100, 150, 200, 250, 300, 350, 400]
HashCode = -1818371895
