<h1>Using java.time</h1>

The modern approach uses the java.time classes rather than the troublesome old legacy date-time classes (<code>Date</code>, <code>Calendar</code>, etc.).

The <a href="https://docs.oracle.com/javase/8/docs/api/java/time/LocalDate.html" rel="nofollow noreferrer"><code>LocalDate</code></a> class represents a date-only value without time-of-day and without time zone.

Define a formatting pattern to match your input strings using the <code>DateTimeFormatter</code> class.

<pre><code>String input = "15/03/2014" ;
DateTimeFormatter f = DateTimeFormatter.ofPattern( "dd/MM/uuuu" );
LocalDate ld = LocalDate.parse( input , f );
</code></pre>

<blockquote>
 ld.toString(): 2014-03-15
</blockquote>

To specify a fixed date, pass year, month, and dayOfMonth. For the month, you may specify a number, sanely numbered 1-12 for January-December (unlike the crazy 0-11 in the legacy classes!). Or you may choose to use the <a href="https://docs.oracle.com/javase/8/docs/api/java/time/Month.html" rel="nofollow noreferrer"><code>Month</code></a> enum objects.

<pre><code>LocalDate firstOf2014 = LocalDate.of( 2014 , Month.JANUARY , 1 );
</code></pre>

Compare using <code>isBefore</code>, <code>isEqual</code>, or <code>isAfter</code> methods.

<pre><code>Boolean isInputDateBeforeFixedDate = ld.isBefore( firstOf2014 ) ;
</code></pre>

<blockquote>
 isInputDateBeforeFixedDate.toString(): false
</blockquote>

<h1>ISO 8601</h1>

If possible, replace your particular date string format with the standard <a href="https://en.wikipedia.org/wiki/ISO_8601" rel="nofollow noreferrer">ISO 8601</a> format. That standard defines many useful practical unambiguous string formats for date-time values. 

The java.time classes use the standard formats by default when parsing/generating strings. You can see examples in the code above. For a date-only value, the standard format is YYYY-MM-DD.

<h1>About java.time</h1>

The <a href="http://docs.oracle.com/javase/8/docs/api/java/time/package-summary.html" rel="nofollow noreferrer">java.time</a> framework is built into Java 8 and later. These classes supplant the troublesome old <a href="https://en.wikipedia.org/wiki/Legacy_system" rel="nofollow noreferrer">legacy</a> date-time classes such as <a href="https://docs.oracle.com/javase/8/docs/api/java/util/Date.html" rel="nofollow noreferrer"><code>java.util.Date</code></a>, <a href="https://docs.oracle.com/javase/8/docs/api/java/util/Calendar.html" rel="nofollow noreferrer"><code>Calendar</code></a>, &amp; <a href="http://docs.oracle.com/javase/8/docs/api/java/text/SimpleDateFormat.html" rel="nofollow noreferrer"><code>SimpleDateFormat</code></a>.

The <a href="http://www.joda.org/joda-time/" rel="nofollow noreferrer">Joda-Time</a> project, now in <a href="https://en.wikipedia.org/wiki/Maintenance_mode" rel="nofollow noreferrer">maintenance mode</a>, advises migration to the <a href="http://docs.oracle.com/javase/8/docs/api/java/time/package-summary.html" rel="nofollow noreferrer">java.time</a> classes.

I am taking in two dates as command line arguments and want to check if the first one is after the second date. the format of the date it "dd/MM/yyy".
Example: java dateCheck 01/01/2014 15/03/2014
also i will need to check if a third date hardcoded into the program is before the second date.

how to check if one date is after another in java?

我接受两个日期作为命令行参数，并希望检查第一个日期是否在第二个日期之后。日期的格式为"dd/MM/yyy“。例如: java dateCheck 01/01/2014 15/03/2014我还需要检查硬编码到程序中的第三个日期是否在第二个日期之前。

问如何在java中检查一个日期是否在另一个日期之后？
