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() methodimport 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() methodimport 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
