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
