How do I parse this date format in Java?

Jordan Bancino :

I am clearly missing something but I don't know what. I wrote this example program that replicates a problem I'm having:

import java.util.Date;
import java.text.SimpleDateFormat;

public class TestDate {
    public static void main(String... args) throws Exception {
        // The input date format
        SimpleDateFormat iF = new SimpleDateFormat("MMM dd YYYY HH:mm");
        // The output date format
        SimpleDateFormat oF = new SimpleDateFormat("YYYY-MM-dd'T'HH:mm:ssXXX");
        // Parse an input date and format it
        System.out.println(oF.format(iF.parse("Aug 26 2020 18:00")));
    }
}

When I run it, the output is this:

2020-12-29T18:00:00-05:00

The time and time zone are correct, but why is the date December 29 when I clearly input August 26?

Please refer to the SimpleDateFormat documentation and see if you can figure out what I am doing wrong. I've tried using L in place of M like the documentation suggests, but I get the same result.

Use yyyy instead YYYY:

public static void main(String... args) throws Exception {
    // The input date format
    SimpleDateFormat iF = new SimpleDateFormat("MMM dd yyyy HH:mm", Locale.US);
    // The output date format
    SimpleDateFormat oF = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ssXXX");
    // Parse an input date and format it
    System.out.println(oF.format(iF.parse("Aug 26 2020 18:00")));
}
