Regarding Date class in java

Question

Whenever I am providing different date to the program it's always gives output as wrong date. Its showing the previous year December month date.

import java.text.*;
import java.util.*;

public class Sample {

    public static void main(String args[])throws Exception 
    {
        Scanner s = new Scanner(System.in);
        System.out.println("Enter the details");
        String str = s.nextLine();
        String v[] = str.split(",");

        System.out.println(v[0]);
        System.out.println(v[1]);
        System.out.println(v[2]);
        try{
            Date d1 = new SimpleDateFormat("dd/MM/YYYY HH:mm:ss").parse(v[0]);
            Date d2 = new SimpleDateFormat("dd/MM/YYYY HH:mm:ss").parse(v[1]);


            System.out.println(v[0]+"  =  "+ d1); 
            System.out.println(v[1]+"  =  "+d2); 
        } catch(Exception e) {
            e.printStackTrace();
        }
    }
}

run:

Consider using `java.time` package. The classes you use are obsolete and hard to use. https://www.baeldung.com/java-8-date-time-intro — parsecer, Jul 05 '19 at 20:49
Always **search Stack Overflow** thoroughly before posting. Learn from existing code examples, study how those match or differ from your own code. — Basil Bourque, Jul 05 '19 at 22:08

I believe the issue is with the year pattern. Try the following instead:

  Date d1 = new SimpleDateFormat("dd/MM/yyyy HH:mm:ss").parse(v[0]);

You should use lowercase yyyy for "year". Uppercase Y represents "week year", see How does Java "week year" really work?
