This article shows few examples to compare two dates in Java. Updated with Java 8 examples. 1. Compare two date 1.1 Date.compareTo 1.2 Date.before(), Date.after() and Date.equals() 1.3 Check if a date is within a certain range 2. Compare two calendar 3. Compare two date and time (Java 8) 3.1 Compare two LocalDate 3.2 Compare two LocalDateTime 3.3 Compare two Instant 4 Check if a date is within a certain range (Java 8) 5 Check if the date is older than 6 months References 1. Compare two date For the legacy java.util.Date , we can use compareTo , before() , after() and equals() to compare two dates. 1.1 Date.compareTo Below example uses Date.compareTo to compare two java.util.Date in Java. Return value of 0 if the argument date is equal to the Date . Return value is greater than 0 or positive if the Date is after the argument date. Return value is less than 0 or negative if the Date is before the argument date. Review the Date.compareTo method signature. Date.java package java...

In this tutorial, we will show you how to convert a String to java.util.Date . Many Java beginners are stuck in the Date conversion, hope this summary guide will helps you in some ways. // String -> Date SimpleDateFormat.parse(String); // Date -> String SimpleDateFormat.format(date); Refer to table below for some of the common date and time patterns used in java.text.SimpleDateFormat , refer to this JavaDoc Letter Description Examples y Year 2013 M Month in year July, 07, 7 d Day in month 1-31 E Day name in week Friday, Sunday a Am/pm marker AM, PM H Hour in day 0-23 h Hour in am/pm 1-12 m Minute in hour 0-60 s Second in minute 0-60 Note You may interest at this Java 8 example – How to convert String to LocalDate 1.
