    Default Pasrsing error when comparing two dates

    Im creating a date from Calendar with format ("EEE MMM dd kk:mm:ss z yyyy"); example Mon Nov 29 10:10:50 CST 2021. Im then grabbing a date from linked string/data object in format ("MM/dd/yyyy");. In to convert it to the same format as the Calendar date for use to compare the dates. Im not sure why Im getting this errors. Any help would be greatly appreciated

    Its beanshell with code passing in in xml object.

    Exception: sailpoint.tools.GeneralException: BeanShell script error: bsh.ParseException: Parse error at line 93, column 65. Encountered: ( BSF info: script at line: 0 column: columnNo
    sailpoint.tools.GeneralException: sailpoint.tools.GeneralException: BeanShell script error: bsh.ParseException: Parse error at line 93, column 65.

    which is this block


    try {

    LocalDate acuEffectiveHireDate = mdy.parse(acuEffectiveHireDateString, LocalDate::from);
    LocalDateTime ldt = LocalDateTime.of(acuEffectiveHireDate, LocalTime.of(0, 0));
    ZonedDateTime zdt = ZonedDateTime.of(ldt, ZoneId.systemDefault);

    String formatted = formatter.format(zdt);
    ZonedDateTime parsedAcuEffectiveHire = formatter.parse(formatted, ZonedDateTime::from);
    log.debug("parsedAcuEffectiveHire" + parsedAcuEffectiveHire);

    thresholdDate = getDateNDaysAgo(25);
    log.debug("thresholdDate" + thresholdDate);

    if(parsedAcuEffectiveHire != null) {
    System.out.println("parsedAcuEffectiveHire" + parsedAcuEffectiveHire);
    }

    Sorry, I do not know anything about beanshell.
    If you have a java programming problem please make a SSCCE and paste it here.

    Make a sscce that demonstrates the problem and paste it here.

    I couldn't get it to recognize ZoneId without the specific import:
    import java.time.ZoneId;

    Next in the try block you are using systemDefault but that is a method and needs the ()
    ZonedDateTime zdt = ZonedDateTime.of(ldt, ZoneId.systemDefault());


    A little further down I ran into another problem.
    First I needed the calendar import:
    import java.util.Calendar;

    After that the compareTo line is fouled. You cannot compare Date with ZonedDateTime.
    (I also have no idea how to implement the &lt generics comparison thing so I skipped that until I can learn more about it)
    I ran into bracket nightmare so I split it into two lines:
            ZonedDateTime z = ZonedDateTime.ofInstant(thresholdDate.toInstant(), ZoneId.systemDefault());
            if(parsedEffectiveHire.compareTo(z) < 0){

    The following is the entire code I ran using the online compiler found here
    Please excuse the default class name HelloWorld and the fact that I changed some of the variable names you used.
    import java.text.DateFormat;
    import java.text.SimpleDateFormat;
    import java.util.ArrayList;
    import java.util.Collections;
    import java.util.Date;
    import java.util.Iterator;
    import java.util.List;
    import java.time.*;
    import java.time.format.*;
    import java.time.ZoneId; 
    import java.util.Calendar; 
     
    public class HelloWorld{
     
         public static void main(String []args){
            //System.out.println("Hello World");
            String stringDate = "01/12/21";
            DateTimeFormatter formatter = DateTimeFormatter.ofPattern("EEE MMM dd kk:mm:ss z yyyy");
            DateTimeFormatter mdy = DateTimeFormatter.ofPattern("MM/dd/yy");
            Date date = new Date("SAT DEC 28 01:12:32 PST 1996");
            //Date newDate = mdy.parse()
            LocalDate d = mdy.parse(stringDate, LocalDate::from);  
            LocalDateTime ldt = LocalDateTime.of(d, LocalTime.of(0, 0));
            ZonedDateTime zdt = ZonedDateTime.of(ldt, ZoneId.systemDefault());
            System.out.println(d);
            System.out.println(ldt);
            System.out.println(zdt);
     
            String formatted = formatter.format(zdt);
            ZonedDateTime parsedEffectiveHire = formatter.parse(formatted, ZonedDateTime::from);
            System.out.println("parsedEffectiveHire " + parsedEffectiveHire);
     
            Date thresholdDate = getDateNDaysAgo(25);         
            System.out.println("threshold date " + thresholdDate);
            ZonedDateTime z = ZonedDateTime.ofInstant(thresholdDate.toInstant(), ZoneId.systemDefault());
            if(parsedEffectiveHire.compareTo(z) < 0){
                System.out.println("older than 25 days");
            }
         }
         private static Date getDateNDaysAgo(int numDays) {
                          //log.debug("getDateNDaysAgo 1 " + numDays);
                          Calendar cal = Calendar.getInstance();
                          Date returnDate = null;
                          cal.add(Calendar.DATE, -(numDays));
                          returnDate = cal.getTime();
                          //log.debug("getDateNDaysAgo 2" + returnDate);
                          return (returnDate);
    		   }	
    }

    It really is better to cut out enough code for the forum viewer to simply cut and paste and run.
    This gives you far quicker and better results.
