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() methodimport 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() methodimport 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
