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
