The equals() Method of SimpleDateFormat class is used to compare two SimpleDateFormat objects. The method returns True if this SimpleDateFormat is equal to the passed object else returns False.
Syntax:
public boolean equals(Object obj)
Parameters: The method takes one parameter obj of Object type and refers to the object that is to be compared with this SimpleDateFormat object.
Return Value: The method returns boolean True if both the objects are equal else the method returns False.
Below programs illustrate the working of equals() Method of SimpleDateFormat:
Example 1:
// Java code to illustrate equals() method import java.text.*;import java.util.*; public class SimpleDateFormat_Demo { public static void main(String[] args) throws InterruptedException, ParseException { // Initializing the first formatter SimpleDateFormat SDFormat1 = new SimpleDateFormat(); // Initializing the second formatter SimpleDateFormat SDFormat2 = new SimpleDateFormat(); // Displaying both the Formats Date date = new Date(); String str_Date1 = SDFormat1.format(date); System.out.println("First: " + (str_Date1)); String str_Date2 = SDFormat2.format(date); System.out.println("Second: " + (str_Date2)); // Comparing both the objects System.out.println("Equality: " + SDFormat1.equals(SDFormat2)); }} |
Output:
First: 1/30/19 9:59 AM Second: 1/30/19 9:59 AM Equality: true
Example 2:
// Java code to illustrate equals() method import java.text.*;import java.util.*; public class SimpleDateFormat_Demo { public static void main(String[] args) throws InterruptedException, ParseException { // Initializing the first formatter SimpleDateFormat SDFormat1 = new SimpleDateFormat(); // Defining the SDFormat SDFormat1.applyPattern("MMM"); // Initializing the second formatter SimpleDateFormat SDFormat2 = new SimpleDateFormat(); // Displaying both the Formats Date date = new Date(); String str_Date1 = SDFormat1.format(date); System.out.println("First: + (str_Date1)); String str_Date2 = SDFormat2.format(date); System.out.println("Second: " + (str_Date2)); // Comparing both the objects System.out.println("Equality: " + SDFormat1.equals(SDFormat2)); }} |
Output:
First: Jan Second: 1/30/19 10:00 AM Equality: false
