FieldPosition hashCode() method in Java with Example

The hashCode() method of java.text.FieldPosition class is used to get the hashcode of the FieldPosition object. Syntax:

public int hashCode()

Parameter: This method does not accepts any argument as parameter. Return Value: This method returns the hashcode of this FieldPosition object. Below are the examples to illustrate the hashCode() method: Example 1:

Java

// Java program to demonstrate
// hashCode() method
 
import java.text.*;

import java.util.*;

import java.io.*;
 
public class GFG {

    public static void main(String[] argv)

    {

        try {
 
            // Creating and initializing

            // new FieldPosition Object

            FieldPosition pos

                = new FieldPosition(

                    MessageFormat.Field.ARGUMENT);
 
            // getting hash code of this

            // field position object

            // using hashCode() method

            int i = pos.hashCode();
 
            // display result

            System.out.println("hashCode. :- " + i);

        }
 
        catch (ClassCastException e) {
 
            System.out.println("Exception thrown : " + e);

        }

    }
}

Output:

hashCode. :- -16777216

Example 2:

Java

// Java program to demonstrate
// hashCode() method
 
import java.text.*;

import java.util.*;

import java.io.*;
 
public class GFG {

    public static void main(String[] argv)

    {

        try {
 
            // Creating and initializing

            // new FieldPosition Object

            FieldPosition pos

                = new FieldPosition(

                    DateFormat.Field.AM_PM);
 
            // getting hash code of this

            // field position object

            // using hashCode() method

            int i = pos.hashCode();
 
            // display result

            System.out.println("hashCode. :- " + i);

        }
 
        catch (ClassCastException e) {
 
            System.out.println("Exception thrown : " + e);

        }

    }
