AbstractSequentialList hashCode() method in Java with Example

  • Last Updated : 24 Dec, 2018

The hashCode() method of AbstractSequentialList in Java is used to get the hashCode value for this instance of the AbstractSequentialList. It returns an integer value which is the hashCode value for this instance of the AbstractSequentialList.

Syntax:

public int hashCode()

Parameters: This function has no parameters.

Returns: The method returns an integer value which is the hashCode value for this instance of the AbstractSequentialList.

Below examples illustrates the AbstractSequentialList.hashCode() method:



Example 1:




// Java code to demonstrate the working of
// hashCode() method in AbstractSequentialList
  
import java.util.*;
  
public class GFG {
    public static void main(String[] args)
    {
        // creating an AbstractSequentialList
        AbstractSequentialList<Integer> arr
            = new LinkedList<Integer>();
  
        // using add() to initialize values
        // [1, 2, 3, 4]
        arr.add(1);
        arr.add(2);
        arr.add(3);
        arr.add(4);
  
        // print AbstractSequentialList
        System.out.println("AbstractSequentialList: "
                           + arr);
  
        // Get the hashCode value
        // using hashCode() value
        System.out.println("HashCode value: "
                           + arr.hashCode());
    }
}
Output:
AbstractSequentialList: [1, 2, 3, 4]
HashCode value: 955331

Example 2:




// Java code to demonstrate the working of
// hashCode() method in AbstractSequentialList
  
import java.util.*;
  
public class GFG {
    public static void main(String[] args)
    {
        // creating an AbstractSequentialList
        AbstractSequentialList<String> arr
            = new LinkedList<String>();
  
        // using add() to initialize values
        // [Geeks, For, ForGeeks, GeeksForGeeks]
        arr.add("Geeks");
        arr.add("For");
        arr.add("ForGeeks");
        arr.add("GeeksForGeeks");
  
        // print AbstractSequentialList
        System.out.println("AbstractSequentialList: "
                           + arr);
  
        // Get the hashCode value
        // using hashCode() value
        System.out.println("HashCode value: "
                           + arr.hashCode());
    }
}
Output:
AbstractSequentialList: [Geeks, For, ForGeeks, GeeksForGeeks]
HashCode value: -927254198
