This method is used to generate the hashCode for the given list.
Syntax:
int hashCode()
Parameters: This function has no parameter.
Returns: This function returns the hashCode value for the given list.
Below programs show the implementation of this method.
Program 1:
// Java code to show the implementation of// hashCode method in list interfaceimport java.util.*;public class GfG {      // Driver code    public static void main(String[] args)    {          // Initializing a list of type Linkedlist        List<Integer> l = new LinkedList<>();        l.add(10);        l.add(15);        l.add(20);        System.out.println(l);          int hash = l.hashCode();          System.out.println(hash);    }} |
Output:
[10, 15, 20] 39886
Program 2: Below is the code to show implementation of list.hashCode() using Linkedlist.
// Java code to show the implementation of// hashCode method in list interfaceimport java.util.*;public class GfG {      // Driver code    public static void main(String[] args)    {          // Initializing a list of type Linkedlist        List<String> l = new LinkedList<>();        l.add("10");        l.add("15");        l.add("20");        System.out.println(l);          int hash = l.hashCode();          System.out.println(hash);    }} |
Output:
[10, 15, 20] 1586008
