How to do the Date comparison in Java

**Rock Villa** · 06-08-2009

Two projects have come for Bug fixing, the bug fixing was to calculate the date comparison for two consecutive forms, currently it shows only the difference between Two dates, I have search for the solution on the internet but does not found anything relevant to my answer. Any suggestion would be appreciated.

Create java.util.Date objects based on the dates that you'd like to compare. To make a program on this example firstly we have to make a class ComparingFileDates. Inside the class we have defined three static variables, which will be used for comparing the files. use "public long getTime()" method of each date object to obtain number of milliseconds since January 1, 1970, 00:00:00 GMT for each date, and compare these long values using operators <, >, ==, <>, != as you see fit.

Inside this method make a two objects of a File class which will take file name as its input in the constructor of File class. Now call the method lastModified by the instances of file classes which will return the time of the file creation. So if you don't like the article then look up the Javadoc API for Calendar.

The program you will use should have the following classes and methods.
File: This class extends class Object and implements Comparable and Serializable interface. It takes the file as its input.
