Below programs illustrate the working of hashCode() Method of SimpleDateFormat:
Example 1:
// Java to illustrate hashCode() method import java.text.*; import java.util.*; public class SimpleDateFormat_Demo { public static void main(String[] args) throws InterruptedException { // Initializing SimpleDateFormat SimpleDateFormat SDFormat = new SimpleDateFormat( "dd/MM/yyyy" ); // Displaying the formats Date date = new Date(); String str_Date1 = SDFormat.format(date); System.out.println( "The Original: " + (str_Date1)); // Displaying the hash code System.out.println( "The hash code: " + SDFormat.hashCode()); } } |
Output:
The Original: 30/01/2019 The hash code: -650712384
Example 2:
// Java to illustrate hashCode() method import java.text.*; import java.util.*; public class SimpleDateFormat_Demo { public static void main(String[] args) throws InterruptedException { // Initializing SimpleDateFormat SimpleDateFormat SDFormat = new SimpleDateFormat( "MM/dd/yyyy" ); // Displaying the formats Date date = new Date(); String str_Date1 = SDFormat.format(date); System.out.println( "The Original: " + (str_Date1)); // Displaying the hash code System.out.println( "The hash code: " + SDFormat.hashCode()); } } |
Output:
The Original: 01/30/2019 The hash code: 2087096576
