Question

A search API is returning date in String format,I want to compare that date with current date and do something. I created a date object and parsed it but still getting error when I do the compare.

Calendar currentDate = Calendar.getInstance();
long dateNow = currentDate.getTimeInMillis();

String eventDate = meta.getString("startDate"); //This is the string API returns

SimpleDateFormat formatter  = new SimpleDateFormat("yyyy-MM-dd kk:mm:ss.SSS");
Date date = formatter.parse(eventDate);
long modifiedDate= date.getTime();

if (dateNow.compareTo(modifiedDate)>0) {
    //Do Something
}                            

Error I get is :

Cannot invoke compareTo(long) on the primitive type long

Thanks.

Answer 1

When comparing primitive longs just use a vanilla comparison operator:

dateNow > modifiedDate

This is not recommended, but if you want to use compareTo, first convert to Long:

Long.valueOf(dateNow).compareTo(Long.valueOf(modifiedDate)) > 0
