Convert Current date to integer

Question

I want to convert the current date to integer value. By default, it returns long. When I try to convert long to integer, and afterwards I convert the integer value to date,

Answer 1

Java Date to int conversion:

public static final String DATE_FORMAT_INT = "yyyyMMdd";

public static String format(Date date, String format) {
    return isNull(date) ?  
    null : new SimpleDateFormat(format).format(date);
}

public static Integer getDateInt(Date date) {
    if (isNull(date)) {
        throw new IllegalArgumentException("Date must not be NULL");
    }

    return parseInt(format(date, DATE_FORMAT_INT));
}
