Java Calendar method after() to after different field values to date object

Date

Calendar.after(date obj) Check by comparing the calendar with the date represented.

date obj : Required Calendar date object, represented.
Returns boolean , true if the date is after the Calendar date object , false otherwise.

Examples with output
Let us find out the current date , then compare this with the given ( input ) date.

package my_proj;
 
import java.util.Calendar;
 
public class my_first {
public static void main(String[] args) {

  
Calendar my_cal = Calendar.getInstance();// created calendar 
Calendar my_present_date=Calendar.getInstance();
System.out.println("Current Date is : " + my_present_date.getTime());

//Year, Month, Date, Hour, Minute, Second
my_cal.set(2020,2, 2); // Input date
System.out.println("Input date is :" + my_cal.getTime());

System.out.println(my_cal.after(my_present_date));//true
}
}

Output is here

Current Date is : Sun Mar 01 08:49:19 IST 2020
Input date is :Mon Mar 02 08:49:19 IST 2020
true

This output will change based on the current date and input date you use in your script. As you can see we tested this program on Mar 1^st by using input date as 2^nd of March ( same year ), we got the output as true.

Including time

We will add Hour , minutes and Seconds to our comparison. We have kept the minutes part more than the current minute, so we get true as output.

package my_proj;
 
import java.util.Calendar;
 
public class my_first {
public static void main(String[] args) {

  
Calendar my_cal = Calendar.getInstance();// created calendar 
Calendar my_present_date=Calendar.getInstance();
System.out.println("Current Date is: " + my_present_date.getTime());

//Year, Month, Date, Hour, Minute, Second
my_cal.set(2020,2, 1,9,19,13); // Input date
System.out.println("Input Date  is  :" + my_cal.getTime());

System.out.println(my_cal.after(my_present_date));//true
}
}

Output is here

Current Date is: Sun Mar 01 09:18:58 IST 2020
Input Date  is  :Sun Mar 01 09:19:13 IST 2020
true

With two input dates

Instead of using current date and time we can use two input dates for comparison.
As our first date ( my_cal_d1 ) is not after second date ( my_cal_d2), we will get false as output.

package my_proj;
 
import java.util.Calendar;
 
public class my_first {
public static void main(String[] args) {

  
Calendar my_cal_d1 = Calendar.getInstance();// created calendar 
Calendar my_cal_d2 = Calendar.getInstance();

my_cal_d1.set(2020,2, 1); // Input date
my_cal_d2.set(2020,2, 2); // Input date

System.out.println(my_cal_d1.after(my_cal_d2));//false
}
}
