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);
        }
    }
}

Output:

hashCode. :- -16777216
