Below are the examples to illustrate the hashCode() method:

Example 1:




// 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() mehtod
            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:

// 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() mehtod
            int i = pos.hashCode();
  
            // display result
            System.out.println("hashCode. :- " + i);
        }
  
        catch (ClassCastException e) {
