The equals() method of Java Date class checks if two Dates are equal, based on millisecond difference.
Syntax:
public boolean equals(Object obj)
Parameters: The function accepts a single parameter obj which specifies the object to be compared with.
Return Value: The function gives 2 return values specified below:
- true if the objects are equal.
- false if the objects are not equal.
Exception: The function does not throws any exception.
Program below demonstrates the above mentioned function:
// Java code to demonstrate// equals() function of Date class import java.util.Date;import java.util.Calendar;public class GfG { // main method public static void main(String[] args) { // creating a Calendar object Calendar c = Calendar.getInstance(); // set Month // MONTH starts with 0 i.e. ( 0 - Jan) c.set(Calendar.MONTH, 11); // set Date c.set(Calendar.DATE, 05); // set Year c.set(Calendar.YEAR, 1996); // creating a date object with specified time. Date dateOne = c.getTime(); System.out.println("Date 1: " + dateOne); // creating a date of object // storing the current date Date currentDate = new Date(); System.out.println("Date 2: " + currentDate); System.out.println("Are both dates equal: " + currentDate.equals(dateOne)); }} |
Output:
Date 1: Thu Dec 05 08:19:56 UTC 1996 Date 2: Wed Jan 02 08:19:56 UTC 2019 Are both dates equal: false
// Java code to demonstrate// equals() function of Date class import java.util.Date;import java.util.Calendar;public class GfG { // main method public static void main(String[] args) { // creating a Calendar object Calendar c1 = Calendar.getInstance(); // set Month // MONTH starts with 0 i.e. ( 0 - Jan) c1.set(Calendar.MONTH, 11); // set Date c1.set(Calendar.DATE, 05); // set Year c1.set(Calendar.YEAR, 1996); // creating a date object with specified time. Date dateOne = c1.getTime(); System.out.println("Date 1: " + dateOne); // creating a Calendar object Calendar c2 = Calendar.getInstance(); // set Month // MONTH starts with 0 i.e. ( 0 - Jan) c2.set(Calendar.MONTH, 11); // set Date c2.set(Calendar.DATE, 05); // set Year c2.set(Calendar.YEAR, 1995); // creating a date object with specified time. Date dateTwo = c2.getTime(); System.out.println("Date 1: " + dateTwo); System.out.println("Are both dates equal: " + dateTwo.equals(dateOne)); }} |
Output:
Date 1: Thu Dec 05 08:20:05 UTC 1996 Date 1: Tue Dec 05 08:20:05 UTC 1995 Are both dates equal: false
