MessageFormat hashCode() method in Java with Example

Last Updated : 23 Apr, 2021

The hashCode() method of java.text.MessageFormat class is used to get hashcode for this message format object.
Syntax: 
 

public int hashCode()


Parameter: This method does not take any argument as a parameter.
Return Value: This method returns the hash code for this message format 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)
    {
        // creating and initializing  MessageFormat
        MessageFormat mf
            = new MessageFormat("{0, number, #}, {2, date, #.#}, {4, time}");

        // getting hash code
        // for this MessageFormat Object
        // using hashCode() method
        int hash = mf.hashCode();

        // display the result
        System.out.println("Hashcode is : " + hash);
    }
}

Output: 
Hashcode is : 1408

 

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)
    {
        // creating and initializing  MessageFormat
        MessageFormat mf
            = new MessageFormat("{0, number, #}, {4, time}");

        // getting hash code
        // for this MessageFormat Object
        // using hashCode() method
        int hash = mf.hashCode();

        // display the result
        System.out.println("Hashcode is : " + hash);
    }
}

Output: 
Hashcode is : 44
